Closing In

Interior finishes are underway and finish site work to start soon

Posted on Jan 31 2017 by Carl Seville

Our home construction project is over the hump: drywall and flooring have been installed, exterior trim is wrapping up, and interior trim, cabinets, and tile will be starting soon.

Although things are generally going quite well, and while I am happy with the house, I am not enjoying the process very much. Even after 25 years as a contractor, I don’t deal well with the stress of coordinating dozens of subcontractors and suppliers. Materials don’t arrive when promised, workers don’t finish on schedule, and managing different trades in the house at the same time creates tensions.

All this adds up to a lot of lost sleep at night and waiting around for people to show up and answer calls and emails during the day. I know I will end up with a superior product in the end, but the path there is taking its toll on my sanity.

New and recurring problems

The incompetent framing work continues to haunt us. The exterior trim crew is working diligently to correct out-of-level, out-of-plumb, and out-of-square construction, hiding a multitude of sins with skillful finish work. Few people will every notice the little details that will bother me, and luckily these are all cosmetic at this point and won’t affect the building performance.

Interior trim work will start soon. I believe we have addressed most of the issues inside, but we will only know once installation starts. With a little luck we won’t uncover any major problems.

One issue that I take full responsibility for was the drywall adhesive. I neglected to specify a low-VOCVolatile organic compound. An organic compound that evaporates readily into the atmosphere; as defined by the U.S. Environmental Protection Agency, VOCs are organic compounds that volatize and then become involved in photochemical smog production. product, so when I first walked in the house when the hangers were working I was hit hard with the fumes from the glue they used.

Fortunately, it will dissipate quickly and is unlikely to have any long-lasting effects, but it would have been nice to use a less toxic product. Not being a full-time builder, I don’t have standard specs nor ongoing relationships with trade contractors. Armed with either, this problem could have been easily avoided.

Most green building programs provide points for low-VOC products. Some even require the use of all low-VOC sealants and adhesives in a project. This can be one of the most difficult tasks to accomplish considering how many different trades bring their own products on the jobsite.

Without a guard at the door, inspecting everything that arrives on site, it is challenging to keep all high-VOC products off the job. I have specified no added urea formaldehydeChemical found in many building products; most binders used for manufactured wood products are formaldehyde compounds. Reclassified by the United Nations International Agency for Research on Cancer (IARC) in 2004 as a “known human carcinogen." material for cabinets and closet shelf systems, and low- or zero-VOC paints and floor finishes. I'm still waiting for the specifications on some of those products. I plan on not being shocked at odors when I walk in the house again.

Looking inward

Other than a small scheduling snafu with drywall finishers and floor installers on site at the same time, the interior work is moving along well. I installed Owens Corning blown-in fiberglass insulation in the walls behind netting and fiberglass batts in most of the rim joists.

The installers did a good job over two long days, with my close supervision on the installation of the batts (after I caught them doing a typical Grade 3 cram-it-in-as-fast-as-they-can method). Luckily they were receptive to my instructions about cutting to fit around pipes and wires.

We wrapped up in the dark with headlamps lighting the way. Attic insulation will go in later — R-50 loose fill over the Zip SheathingMaterial, usually plywood or oriented strand board (OSB), but sometimes wooden boards, installed on the exterior of wall studs, rafters, or roof trusses; siding or roofing installed on the sheathing—sometimes over strapping to create a rainscreen. we installed on top of the second-floor ceiling joists. One minor issue in the attic is the vent baffles: although they are installed and are high enough to go over the top of the insulation, as installed, they don’t block off the soffit, so additional work will need to be done before we can insulate.

Luckily climate change is cooperating and giving us spring-like temperatures much of this winter. Except for a short cold snap that delayed the finishers before our current 70+ temperatures, drywall was installed and finished efficiently by a very professional crew. Two small electric space heaters kept the house from getting too cold for a few days, thanks to the tight and well-insulated envelope.

Wood floors are installed. Since the entire house is on a slab and I wanted site-finished wood, we installed plywood on the slab, nailed through the Polyguard Term vapor and termite barrier, which was then treated with Boracare. We had some nail pops that took some work to correct, but the floor went in well, and so far there are no noticeable squeaks or soft spots.

Interior doors and trim, ceramic tile, and cabinet installation all start soon, so I expect the activity and my stress level to rise along with the activity inside.

Moving out(side)

As exterior trim is wrapping up, we will finally have enough space on the site to start masonry and driveways. Thin veneer brick will be installed on the concrete foundation in order to avoid having a ledge extending out past the siding; a brick stoop will go in at the front door; a walkway will extend to the sidewalk; and short planter walls will be installed at the rear of the house.

The main driveway will be pervious concrete — necessary to comply with local impervious surface requirements — and pervious brick pavers will create a patio area that will double as a driveway to the carport.

If the weather and trade contractors cooperate, we’re hoping to wrap up construction and move in by early April. Since Decatur requires a green certification certificate to issue a Certificate of Occupancy, we will likely wrap up EarthCraft and NGBSNational Green Building Standard Based on the NAHB Model Green Home Building Guidelines and passed through ANSI. This standard can be applied to both new homes, remodeling projects, and additions. certification quickly, and deal with the LEEDLeadership in Energy and Environmental Design. LEED for Homes is the residential green building program from the United States Green Building Council (USGBC). While this program is primarily designed for and applicable to new home projects, major gut rehabs can qualify. certification later since that is a much slower process.

Fiberglass
by Steve Knapp CZ 3A Georgia

Looking good, Carl. I remain concerned about airborne fibers from the fiberglass. I'm sure you considered this issue. What persuaded you that it wasn't going to be a problem?

Fibers
by Carl Seville

Steve - All insulation has pros and cons, and I decided to give fiberglass a try to see how well the building would perform without having to resort to spray foam. Fiberglass is mostly an irritant, and by the time the house is complete and aired out, there won't be many if any fibers left floating around in the air as they will all be sealed into the drywall.
