Beyond Pricing-Punch List Process?

I touched a little earlier on the need to look beyond just a builder’s price:

  • What are the line item allowances
  • What is the change order process
  • How is the 1-year punch list process handled/managed?

In this day and age, especially with a tough market, some builders are trying to cut profit margins by pricing each job out with different suppliers and trade vendors. But what does that do to the overall loyalty and customer service for each client?  More often than not, you hear horror stories from homeowners, both high and low-end, running into problems after they move into the house that they can’t get resolved.  Our theory is that this is mainly due to a lack of mutual loyalty and respect between the builder and suppliers/trades.  If the builder is shopping around and responding to the lowest vendor, what is the likelihood of that vendor being accessible – or even in business –  in the year after the homeowners have moved in?  We tell people all the time that the 1-year period after moving in as almost as important as the 6-month building process. I would suggest to any homeowner that they need to add the following questions to their qualifying process:

Do you use the same suppliers/trade vendors? How long have you worked with them?

What is the likelihood that they will still be in business the year after our house is built?

Are they local vendors to be able to service urgent needs – such as plumbing leaks or the AC going out in the middle of summer?

Are they accessible 24/7 vs. Mon-Fri, 9-5?

A benefit to using the same vendors, in addition to the accessibility they tend to offer during the 1-year punch list period, is that they tend to work well together and have open communication when building your home. This can minimize any “trade conflict” (such as low voltage interfering with high voltage wiring). All of these factors should be addressed when interviewing builders.

At Absolute Construction and Development, LLC we have used the same suppliers/trades since we started building in NC.  We feel that by giving them our loyalty we in turn receive exceptional workmanship, customer service and the knowledge that they will go above and beyond to meet our expectations. There have been times where we’ve called one of them at 8:00pm on a Saturday and have had them at the home by 10:00am the very next day.  You don’t get that kind of service and loyalty when you are constantly swapping out trade vendors.

  “We were lucky: Our home building process went smoothly due to Lisa and Nelu’s amazing communication and attention to detail. Perhaps the most interactive portion of the process for us came after we moved in. The punch list seemed a little overwhelming at first but Lisa and Nelu really made it easy. All of the things that make them successful were so obvious to us while we worked together on the punch list. The first one wraps up all the details of the build and ensures that your brand new house is shiny and perfect. But, a lot happens in that first year of your new home – with each passing season, your home settles, swells and moves just a little – cabinet doors crack, hardwood floors separate and nail pops need fixed and repainted. Almost a year after you move in, you might expect your builder to care just a little less about your home but this couldn’t be further from the truth with Absolute Construction. Our happiness and satisfaction were just as important to them at that one year mark as it was when we were negotiating the contract. I think that’s amazing and I would recommend Absolute Construction to anyone.”  Michael and Brianne K., Pittsboro, NC

Foam Insulation – The Hidden Super Construction Material

Current conventional insulation, fiberglass and cellulose, are readily available in rolls or blown forms. While, conventional insulation provides some form of resistance to heat transfer, its overall effectiveness needs significant improvement.  Approximately 40 years ago, foam insulation was first introduced into the construction industry. The initial introduction was plagued with problems, off gas of formaldehyde and VOCs, material shrinkage, and sensitivity to off gassing chemical and VOCs. However, through years of improvements in research and development, raw material quality and installation equipment, the development of open cell and closed cell foam have significantly improve thus greatly improving the ability to insulate a home/building.

When addressing heat transfer into and out of a housing/building structure, one needs to address all three forms of heat transfer:

  1. Conduction – conduction is the transfer of heat through a solid member such as studs in your walls and roof, sheathings, etc… The resistance to conductive heat transfer (R-values) is the current standards used for by the industry to measure the effectiveness of the insulation.
  2. Convection – convection is the transfer of heat through a viscous material such as air. Regardless of the R-values, if the insulation material allows air to transfer/move through it, its overall insulation effective performance is significantly diminished. How effectively a structure have been built to resist convective heat transfer can be measured through the use of “blow door testing”
  3. Radiant  – radiant heat transfer is the transfer of heat through energy waves. For example, the roof from a conventionally vented attic absorbs heat energy from the sun and heats up to temperature in excess of 160 degree F. The heat is then transferred through the roof sheathing and studs through conductive heat transfer and then re-radiate inward into the attic. The result is an attic with temperature in excess of 130 degree F or more. While reflective sheathings and reflective foil claims to reduce the heat by 17 to 30%, a foam insulated attic will stop up to 95% of total heat transfer into the attic.

Why is R-value not a true representative example of insulation values?

In a conventionally insulated home, conductive heat transfers only accounts for about 10-20% of the total heat lost and gains. Convective heat lost can accounts for as much as 60% of the total heat lost and heat gains. In addition, radiant heat transfer (heat gains from the sun’s radiant energy) will account for the remaining 20-30%. Furthermore, the R-values of conventional insulations are tested in a laboratory setting and does not take real life conditions into account.  Studies have shown that fiber glass insulation installed where air transfer are allow to circulate through it, will performed only at 30-50% of the claimed insulation values (ie. An R 13 in the exterior walls is only as effective as an R-5 to R-7 in actual performance value.) It is this author’s opinion that the department of Insurance and Department of Energy reconsider the current and obsolete manor for determining the true insulated values of an insulation  by taken into account not just resistance to conductive heat transfer (R-values), but also heat lost and gain through convective and radiant heat transfer. Oak Ridge National Laboratory (ORNL) conducted an experiment (*) to determine the efficiency of a roof assembly insulated with low density, loose-fill fiberglass insulation and discovered that up to 50% of the heat loss occurred as a result of convection; air circulation through the insulation. This result showed that the air-permeable insulation had loss its anticipated thermal performance level by half and that convective heat transfer had a significant negative impact on insulation performance.

Closed Cell (Medium Density) Foam vs Open Cell (Low Density) Foam.

There currently exist two types of foam being use in residential applications: Open cell – Low density foam, and Closed Cell – Medium density foam. There are positive and negative to both products:

Open Cell Positives:

  • High thermal efficiency, performed at 98% of prescriptive R-values
  • Lower cost – approximately 50% the cost of closed cell foam for same prescriptive R-values
  • Same thermal efficiency as closed cell at half the cost
  • Is a registered air barrier at 3.5” for most open cell foam
  • Cured in under 1 minute
  • Has zero off-gas
  • Does not create dust
  • When engineered with the HVAC system: provides for a healthy, energy efficient, low humidity, and comfortable indoor air quality
  • Adds toward building structure strength
  • Is a durable building material – certain manufactures will guarantee the product for the life of the structure
  • Excellent at suppressing audible noise
  • Has low environmental effects


Open Cell Negative:

  • Is not a vapor barrier, so in northern climate zones a vapor barrier (6 mil plastic) is required on the inside of the thermal envelope
  • Some open cell foam product will wick water, if this trait is high in a foam product, it could lead to water issues if house is not properly dried in (seek out hydrophobic foam products)
  • Requires significant trimming and has large quantity of waste

 Closed Cell Positive:

  • Higher R-values per inch when compared to conventional insulation and open cell foam.
  • Is a vapor barrier
  • Provide significant strength to building
  • Excellent at suppressing audible noise
  • Is a durable building material – certain manufactures will guarantee the product for the life of the structure
  • Does not create dust
  • Is a vapor and air barrier

Closed Cell Negative:

  • Extensive period of off-gas (up to 2 years)
  • Not recommended for people with sensitivity to chemicals, allergy, or have respiratory issues
  • VOCs
  • In North Carolina, the vapor barrier is placed on the wrong side of the building
  • Closed cell foam underneath roof can result in roof rot is roof leaks occur
  • Experienced company like Healthy Home Insulation, LLC who installed both open and closed cell foam has made it a practice to not utilized closed cell foam in residential application due to the health water damage liabilities.


As a consumer, we can significant reduce utility cost for heating and cooling our new and existing homes by 50-70%. We can live in a home with superior indoor air quality, is quiet and comfortable. Foam insulation is the most energy efficient insulation product currently available in the market. The use of foam insulation should however, must be incorporated into the house as a system and not use just as a single building product. Correct sizing of the HVAC system(s) by an experience HVAC contractor or building engineer is strongly recommended and will provide for maximum energy efficiency, long-Gevity of the HVAC equipment, proper ventilation and dehumidification of indoor air quality, comfort and a healthy indoor air conditions. Foam insulation is one of the very few building product that can provide an immediate return on investment for new construction and has a ROI in existing retrofit projects in as little as two years.

Why Does Everyone Want an ENERGY STAR Home?

“ENERGY STAR?  I thought that was just for refrigerators!”

As many people now realize, the ENERGY STAR program isn’t just for appliances; it’s also a respected energy efficiency program for new homes and is the basis for most green home programs. Based on building science, the ENERGY STAR new home program has strict guidelines for energy efficiency set by the US Environmental Protection Agency. 

ENERGY STAR qualified homes feature:

  • Properly-installed, advanced insulation
  • High-performance windows
  • High-efficiency and correctly-sized heating and cooling equipment
  • Tightly-sealed ducts and tight construction. 
  • Independent testing and inspections for compliance by a third-party company

Why do these features make such a big difference?

Properly-installed insulation helps keep temperatures even throughout the house, increasing comfort and lowering energy bills.  Building science research has shown that even small deficiencies in insulation installation make a significant difference in insulation performance – and almost all non-ENERGY STAR homes have poorly-installed insulation. Every ENERGY STAR home’s insulation is inspected by an independent rating company and if it is not up to ENERGY STAR’s standards, it has to be fixed.

Advanced, high-performance windows use protective coatings and improved frame assemblies to help keep heat out during the summer and in during the winter.  They also block damaging ultraviolet rays that can discolor carpet and furniture.

High-efficiency and correctly-sized HVAC systems use less energy and help increase comfort in a home.  Correct sizing insures efficient performance and lowers bills.  Especially important in North Carolina, proper sizing helps reduce humidity levels in your home, increasing comfort and decreasing energy bills.

Tightly-sealed ducts make a huge difference in both comfort and indoor air quality while lowering energy bills.  Leaky ducts can introduce pollutants, moisture and mold into a house and if leaky ducts are in your crawl space, that crawl space air is being pulled into your home.  In addition, duct leaks can cause unbalanced pressures that increase air infiltration into your home. In some studies, sealing ducts reduced cooling bills by about 33%.

Tight construction increases comfort and decreases energy bills. A tight house is much less drafty and has better indoor air quality.  Air leakage in the top plane of the house sets up stack effect, pulling in air from the bottom part of the house – many times from the crawl space and/or garage.  This leakage can account for 5% to 40% of the costs to heat and cool buildings, so it’s not a minor thing.

Independent testing and inspections by certified home energy raters make sure the home meets ENERGY STAR standards.  Each home is individually inspected and tested by an independent home energy rating company utilizing scientific equipment and state-of-the-art software.  These inspections include at least one insulation and building component inspection before drywall to make sure all the “under the drywall” items meet ENERGY STAR’s specifications. In addition, each home has final diagnostic testing using a blower door and duct blaster to make sure air infiltration and duct leakage are within ENERGY STAR’s limits.  This insures that the new homeowner will have a comfortable, healthy and efficient home.

What Role on the Home Building Team Does the Surveyor Play?

Quality control during the building process protects the client’s investment for the future.

The land surveyor provides several valued services to the new home construction process including boundary surveys, site design, layout, and construction staking. From the top the most important aspect of the surveyor’s role is one of quality control.

An accurate boundary survey discloses any defects of the parcel to be developed such as encroachments, discrepancies in land area, missing boundary corners or undeclared easements. The boundary survey also quantifies the size, shape and dimension of the building envelope as determined by building setbacks, home owner covenants, environmental buffers and
utility easements.  An accurate boundary survey ensures that the buyer’s vision for their new home will work on the chosen parcel.
Well thought out site design serves as an aid to the client and the builder as well. Placement on the lot, drive access, drainage, foundation exposure and floor height above grade are important considerations for the client. The surveyor will provide an initial site layout to the client based on input from the client and the builder. The client and builder typically have comments and suggestions that complete the final layout.
Once the building process is started the surveyor is responsible for the house layout. There is no

margin for error in laying out the footings and foundation for the new home within the building envelope and as per the client’s vision and architectural plans. A layout certified by the surveyor ensures that the home is positioned on the lot correctly and will not encroach into any setbacks,

across lot lines, or be constructed across any easements and will meet all required covenants and community architectural guidelines.
The final as-built survey of the completed construction by the surveyor certifies to the client, the lender and the community architectural review board that the project has been completed as intended and that there are no boundary issues or site issues.
Your home is an investment in the future. A solid team including the builder, realtor, surveyor, architect, and structural engineer ensures that the client receives the best possible service during and after the building process.
