"I recently had my attic insulated by this company and had a great experience from start to finish. The entire process, from the initial energy audit to customer service and the final installation, was smooth, professional, and well organized. The crew was incredibly kind, hardworking, and patient with all of my questions while they were on site. You can really tell this is a business with a family feel — everyone treated us with care and respect, and it made the whole experience much more comfortable. I would recommend."

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"I have done a lot of research into soundproofing and had a quite a few contractors stop by for an evaluation and a quote over the past couple years, and Robert stood out with his friendly demeanor, level of knowledge, and being easy to talk to; he seemed to have good experience in soundproofing and actually knew soundproofing concepts I'd read up on earlier (surprisingly many other drywall contractors were either evasive in rating their confidence in their proposed projects or simply did not have good plans or knowledge of options). He worked with me on a plan to redo a wall separating my bedroom from noisy neighbors, and the result is excellent! Robert and his team have turned a single stud wall into a decoupled double stud wall, with all the right elements for soundproofing, such as quality insulation, acoustic caulk and dampening compound (both by Green Glue), socket putty, etc. Robert's choice of materials was well informed, and the quality of his work was very good, neat, and precise. I could tell he enjoys doing his work well. He cleaned up after the job was done, and the new wall was perfectly plastered--all I had left to do was to paint (which I enjoy doing myself). The total expense was very reasonable for the cost of materials and labor. I also appreciated that Robert always kept me up-to-date on his schedule and coordinated his visits--great communication. Overall, I am extremely pleased with the experience and glad that I found Robert and his team! I can heartily recommend his services for your drywall and related projects! I'd like to also note for general reference that soundproofing is a global project: learn the weak areas where the sound travels--it's frequently not just your walls, but also through your floors and through your ceilings, including from neighbors on the same floor as you! You may think that just fixing one area will solve everything, but sound wave propagation needs to be considered from all directions/sources, and week areas need to be identified: e.g. you may need to redo your wall and your floor, for example, or your wall and your ceiling, or all 3 at once, depending on your exact needs and situation."

"My house needed to be repaired from a huge fire. I was looking for a GC that has extensive knowledge of fire damage. After multiple quotes, I chose WS Builders because the owner was very professional and knew what he was talking about. Wladimir assisted me from beginning to end. We gutted the whole house and replace all the electricity. This was a big project and it was necessary to find a GC who had previous experience in rebuilding a house damaged by fire. I am very please with Wladimir's work ethic and professionalism. He had a quick turnaround and communicated thoroughly to ensure that I fully understand what was going on during the project. I recommend using him if you are looking for somebody with years of experience. Regardless of what job it is, he has the subcontractors to ensure the job is completed in a timely manner."

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
