Wall-Insulation-with-cedar-shinglesWall Insulation Options:

In Boulder, Louisville, Lafayette, Superior and Longmont, most homes built in the 1950s and earlier have no wall insulation, while houses constructed around or during the 1980s have some wall insulation. In homes built through the 1970s, we can often dramatically improve the R-value of walls even if there is currently insulation in the wall. Sometimes builders miss a few areas in brand new homes because they use “low-bid” insulation companies to maintain their profit margin. We can fix these areas to increase your comfort.

We tube-fill or “dense-pack” the walls with blown cellulose insulation on all above grade walls, and use a formaldehyde free fiberglass on any below-grade walls (like in basements) where moisture in the walls is higher. Below are some of the more common walls insulation processes that may apply to your home. Feel free to call or email us to talk about specifics in your home!

Insulating Brick Walls/Insulating Wood or Press-Board Siding Walls

We love insulating brick homes and pleasing clients, who often don’t realize these projects can be done by a skilled crew in one day. First, we drill out a hole a bit smaller than a quarter in the mortar lines towards the top of the walls. We nozzle-fill the walls from the top, and lower down if needed to get good coverage. We then mix up some matching mortar, and patch the holes at the end of the day, as long as it is above freezing. This method achieves a slightly looser pack on the insulation relative to the methods described below, but we guarantee that we will get all the areas in the walls with this method, so you won’t need to break down the interior of your home to do dust protection for an interior insulation job.

Insulating Under Vinyl Siding

Vinyl siding is relatively easy to insulate. As long as it is not too old and brittle, we merely unzip the siding and prop it up gently, drill holes, dense-pack the walls with insulation, and cap the holes. Then we re-zip up the siding, and the process is complete—without having to paint.

Insulating Walls From The Inside Through Drywall

Wall-insulation-from-insideWhen you purchase a new home, or paint the interior of your existing home, installing wall insulation from the inside makes the most sense. Either way, you end up with a comfortable home that can be painted in colors that match your lifestyle.

Our team, or the client, moves all items away from the exterior walls (and any interior walls that need noise reduction insulation) and covers them with plastic or drop cloths. Our technicians drill holes about waist high between every stud bay. We know the maximum pressure to use to dense-pack the walls with blown cellulose insulation. Then we plug the walls and apply drywall mud to the patches. Finally, our drywaller finishes the holes to match the existing smooth or textured walls, which we touch up or fully paint all the walls corner-to-corner—we’re detail-oriented.

The interior process usually involves more steps before and after the insulation installation, so clients often opt for the exterior installation if it’s feasible for their specific home. But the interior method works great for many homes and clients. We meet with you to go over the pros and cons of different options to find the best fit for you and your home.

Important note: Thin wood paneling from bygone decades often isn’t strong enough to withstand the pressure of dense-packing walls, so we upgrade these rooms with new drywall, which most people think looks better anyway. We can do all these things for you because we’re a licensed general contractor with the goal of helping you create the most attractive, comfortable space possible.
