KVL was great to work with. They put a deck on our cabin and came in on time and under budget. They had great ideas for railing options and step design. We had a second project inside to remove a wall, install a header, and replace flooring. It turned out better than we hoped! We would...

Fluency in English was a problem, otherwise the installers were personable and accommodating. They accidentally cut a wire in our security system, so a further contractor had to be hired to fix the problem.

Very responsive and easy to work with. There was a small issue with one part of the install, but they came the next day to remedy it. We had just the gutter guard installed, and so far it seems like a great product.

We were not at the cabinn at the time of installation. Phone contacts with Dylan were very positive. They were to put tip ups on both downspouts, but had put only one on. Phone call to correct was no problem. It will get re-done.

Our kitchen tiled back splash turned out beautifully. It was a very time consuming project because I had inadvertently picked out single tiles rather than tiles on a mesh backing. Roger worked hard to get the project done in a reasonable time period, working extra late to finish. The...

Doorbell Installation questions, answered by experts

Costs depend on area size, material thickness, and site preparation needs.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

They recommend sustainable materials and water-saving fixtures, tailoring choices to balance sustainability and style.

When installing board and batten siding, make sure there is wall sheathing and a moisture-resistant barrier installed. Behind that sheathing should be plywood or OSB for you to nail the boards and battens into. If there isn’t plywood or OSB, you can install vertical furring strips at 1½- to 2-foot intervals to nail the boards and battens to.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.
