I’m a hardworking person who doesn’t like to leave projects half finished or looking sloppy, I can be a bit of a perfectionist. I’ve always fixed and built almost everything I needed myself and I take pride in being self sufficient. I’ve been an electrician for a year and half now and before that I was fabricating aerators for private residences. I have a wife and two children, so I can handle the chaos of a whole house remodel even if you decide to alter any details halfway through.

"Kyle is a professional in all aspects, timely phone calls, getting back to me, and very polite. I reached out to Olmsted Brothers for an insulation quote and he got it back to me right away. I am not ready to proceed right away due to other reasons, but am looking forward to working with Olmsted Brothers in the near future."

"Contacted a few different companies and had two come out to inspect a large crack in the foundation. First company came out and indicated that the foundation had failed and needed piers put in to stablize the foundation. Crawlspace Solutions came in and indicated that they felt there was nothing failing with the foundation and that they could inject the cracks and warranty the work regardless of if there was a larger issue that required piers. Scott was the person that estimated and completed the work. He was extremely responsive and did a very good job of injecting the cracks. When Scott came to quote the work he also offered a price to apply spray foam to the walls and the sill to replace the fiberglass insulation that the previous owner of the house had on the crawlspace walls. Price included in review was to inject 2 cracks and apply the spray foam. Really glad we had the foam insulation put in. Way cleaner, durable and sealed up some areas that the other insulation could not take care of. Scott also spent extra time explaining some other areas to keep an eye out on to help ensure the foundation area is well managed from any further potential issues like down spout discharge locations, hose connections and just general drainage of the property. One of the concerns we had was if we spend all this money on the injection and the foundation ends up needing to have piers put in, how would that impact the warranty. Scott assured us that if any additional settling occurs and the repair fails, they would come back and repair the injected cracks after the foundation was stable."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation FAQs, answered by experts

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
