"Score Construction completed a clean tile installation for me for a reasonable price. They took care of all the extras such as old tile disposal and also did some painting to to complete the job. I am very happy with the work performed. The easiest that I've found to communicate with throughout the job and a clear payment accountability system."

"I was dreading this work being done due to the anticipated mess since we had a drywall removed to have insulation blown into our attic. The process went fairly quickly. We also had drywall that was cut in our walls to have old insulation removed and new to be blown in. The crew did a lovely job of making the cuts so getting our drywall fixed afterwards was much more simple. All said and done, it wasn't nearly as unpleasant as I had feared. Highly recommend AGL Spray Foam."

"I called Restore You and the owner Art Sulik came to my home at my convenience. He surveyed unerdneath my home and found mold on the floor structure and moisture and water on the ground. He removed the existing insulation, cleaned the wood with hydrogen peroxide product, followed through with an anti microbial. After everything dried they Hepa vac the wood to remove any mold spores which are allergens. Then fogged everything with Timbor fungicide Disodium Ocyabotate tetrahydrate (boron). The foundation walls inside the crawlspace were painted with Dry lok extreme, a waterproof paint. A vapor Barrier 6 Mil was added to the ground. His work was exceptional! I was very pleased. I highly recommend Restore You for any moisture, mold or water problems."

Insulation FAQs, answered by experts

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

Yes, products made from renewable resources and with reduced chemical impacts.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.
