"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

"I was referred to this company from a friend that used them in the past. I needed to remove part of drywall and replace the insulation inside due to a leak from one of the pipes. At first I called the office and told them what the problem was. The office sent Juan to my house to check and see the job. Juan came over the following day and looked the problem. He was able to give me a quote on the spot. 
The price seem to be fair so I hired them for that job. Juan than scheduled me for 2 days later and he told me that it will take 1 day to complete and another day to paint. 
I was happy with the fact that he came over when he said he will and he did complete the job the same day. The paint work was completed the following day and I?m happy with the results.

"Every person that came into our home from Tri-County was very professional and respectful.  They covered everything with plastic before removing the insulation and again when blowing it back in.  They cleaned up and disposed of the plastic, vacuumed the attic and cleaned up after themselves such that  you would never have known they were here.  The job of sealing the attic was done so well that the inspector made a comment that he had never seen a job done as well as this and ask who had done the work.  He gave them very high praise.  

The salesman we had, Bryan Zailer, was very knowledgeable and helpful.  He would call back immediately if we had a question and stop by to check on things.  I would highly recommend Tri-County to everyone for their insulation needs."

"Job was performed as promised, but in process installer stepped through ceiling causing a large hole about 3x3 ft. over family room. Temporarily fixed, but not finished. Withheld some of the original estimate funds until ceiling is completely repaired. Promised to follow up with another contractor. Insulation was blown in per specification. Have not had time to evaluate the savings in energy costs. Communication between the original estimator and installation crew was lacking some information previously provided. Asked for an afternoon appointment, but came in the morning. Did not matter however, as this was a holiday."

Drywall Insulation FAQs, answered by experts

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

When you are learning how to tape and mud drywall, waiting for things to dry requires a lot of patience. So how long does drywall mud take to dry? On average, it takes about 24 hours. However, it depends on things like the thickness of the mud, as well as the room’s temperature, humidity, and ventilation. Using thin layers of mud in a warm, low-humidity room with good airflow reduces average drying time. You also could speed up drying time by making use of hot drywall mud, which consists of a powder that you mix with water, instead of using pre-mixed mud. 

If you want to reduce sound transmission throughout your home, soundproofing drywall is a better choice than standard drywall. However, simply installing soundproofing drywall may not completely block out noise. You’ll get the best results from incorporating it into a larger soundproofing plan that includes proper insulation and framing studs.

You can take a few steps to save money on drywall installation, even when hiring a professional to do the bulk of the work for you. These ideas include the following:

  • Buy the drywall and other materials yourself to avoid product markup and delivery fees

  • Ask about discounts if you use the same company to tape, spackle, and paint

  • Hire drywall professionals in the winter when demand is the lowest

  • DIY as many parts of the project as possible, like replacing insulation and painting

Furring strips, thin strips of wood or metal, are not always required for ceiling drywall installation. If the ceiling surface is even and in good condition, drywall can be directly attached to the ceiling joists using screws. However, furring strips become essential when dealing with irregular surfaces or when additional insulation or soundproofing is needed. They create a level substrate for attaching the drywall. Ultimately, the decision to use furring strips depends on the condition of the existing ceiling and the specific requirements of the project.
