"I have a construction background but was unfamiliar with encapsulation as I just moved to Georgia. After extensive review of the encapsulation systems that were available in the area, and the price difference, I concluded the Crawl Space Doctor was a good fit. The main reason I chose the Crawl Space Doctor was because of their system. The other system was double the cost of the Crawl Space Doctor, so I carefully reviewed the difference and felt I would be getting equal benefits. I selected a 90 mil film for my project. Greg was very prompt and articulate in explaining his system and how his team would complete the work. Greg and his team did excellent work. They took out all of the debris under the house, informed me of a few problems they detected and repaired, then went to work putting the encapsulation system in place. They were very efficient. The crawlspace is doing exactly what I expected. The benefits of the Crawl Space Doctor's system are these: I am breathing better air quality. I am noticing a difference in the temperature of the house with reduced cooling costs, and expect the same on my heating costs. My insulation and floor joists are no longer moist and susceptible to mold. My heating and cooling ductwork will last longer with the humidity gone from the area. The dehumidifiers Greg put in do not run continuously, they will cycle off once the humidity desired point is reached. My hardwood flooring will not buckle in the future due to excessive humidity. My vents are now permanently sealed so rodents can't come into the house in the winter. I have peace of mind knowing my home is more protected with an encapsulation. It is a no brainer product in that it is a good investment all around. I would highly recommend Greg and his team at the Crawl Space Doctor. He has been doing encapsulations for years and is an expert in the field. His team does the work, but he personally oversees the project. You are in good hands with Greg McBride of the Crawl Space Doctor!! You will not regret spending less for top quality!"

Drywall Insulation FAQs, answered by experts

A 50-pound mirror can be hung on drywall, but only if it has the support of strong hardware. Ideally, you can find the studs behind the drywall and attach the mirror to them; this will give your mirror better stability. Otherwise, confirm that you are using anchors appropriate to the weight of the mirrors. Another technique is to use French cleats—two pieces of wood that fit together, with one piece attached to the wall and the other to the mirror. This allows the weight to be distributed over a wider area.

If you’re installing new drywall, you may need to skim coat the drywall first for a smooth finish and to allow the primer to adhere to the wall. It’s only necessary if there are imperfections in your drywall due to issues with the studs or improper drywall installation. If you’re refreshing existing walls, you may want to skim coat if there are imperfections across the wall. As an alternative, you can repair your drywall and sand it for a smooth finish before painting.

You can put drywall mud over paint to even out the surface or entirely resurface it. Sand the surface with 280-grit sandpaper, vacuum the debris and dust with a shop vac, and clean it with a slightly damp cloth. Allow the surface to dry. Apply drywall primer, especially if you’re skim-coating an entire wall. Apply the right type of drywall mud over the surface and smooth it with a trowel. Allow the layer to cure fully, then sand it before applying another layer or painting it.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.

While you can put new drywall over old drywall, it’s not always the best option. In some cases, drywalling over drywall can make it harder to find wires and pipes behind your walls and conceal more serious problems with your walls. It can also make the room smaller. On the plus side, putting drywall over drywall can improve soundproofing and insulation. Plus, it’s often less expensive than tearing down and adding new drywall.
