"Really excellent work insulating an old house with dormers and limited headroom. The attic living space is noticeably improved by the insulation and the rest of the house maintains a more constant temperature. The workers were pleasant, the folks I was in touch with from the office were communicative. Overall, I would recommend Brittin Built for this kind of project."

"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"This company was extremely reliable and worked very fast to get the job done. We used them to renovate an apartment for rent and they were honest with their prices and even suggested options to save us money. We would definitely utilize them in the future and recommend them. I wish I had taken before and after pictures to show what a great job they did. Also, we were really impressed that the contractor sent us pictures and contacted us every time they completed anything."

"I was seeking a significant augmentation of insulation in my attic, since the existing insulation was 31 years old, and had become very thin, and shoved around over several decades of work up there. After vetting 4 contractors, I chose Western Pest Services, and was very pleased with the entire process. they did a thorough evaluation of the attic space, evaluated my plan to run the installation tube through a 2nd floor window, and confirmed that there are no pests in the space. I felt that the price was fair - and the technicians did a terrific job in less time than I had expected. Definitely recommend them!"

"I hired AGL to insulate my basement. When they first came out, they found a water issue in the walls. Instead of just spraying anyway, they advised me to wait a few days for it to dry and do something about the water. I had my contractor add a concrete barrier around the house to keep water away from the walls, and they came back a few days later to do the job. They also left me commercial fans to help dry the place out. They did a great job on the foam, and my basement is extremely well insulated. Sometimes it's warmer down there than in the rest of the house! I'd use them again any day."

"Steve calmed my fears and did the job in two phases at a great price. First all Mold was removed. Second Steve’s Cree came out and built the French Drain in my basement. In both occasions Steve’s crew came out on time and worked very hard to get the job done. Steve kept in constant contact with me during the process and sent pictures of the completed job. I highly recommend Steve for his professionalism and Honesty."

"Due to below freezing temperatures this winter, I had a pipe in my garage burst (the pipe was garage facing, not behind the walls). While I was thankfully home when this occurred and shutoff the water within 10-15 minutes, portions of my drywall got soaked, leading to cosmetic damage. However, I wasn't sure if a longer term consequence of major structural damage or mold would occur. After inspecting the drywall, Larry saw no indication of mold or major structural damage (3 months after the incident), and gave me a few suggestions on how to fix the cosmetic damage by making a quick Home Depot run. Larry could easily have quoted me to gut and replace an entire wall's worth of drywall, but instead, walked me through a fairly inexpensive DIY fix and told me to give him a ring back if anything changed over the summer. I would absolutely recommend Doyle Drywall."

Insulation FAQs, answered by experts

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.
