"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."

"Glenn from Total Home Interiors did some work for my home in October. He helped me reduce sound travelling from my living room and dining areas on the ground floor down into a bedroom in the basement which was directly below. Its an old house, built in 1908 but was renovated about 15 years ago. Being a well insulated foundation, there was no insulation in the walls or ceiling so the noise traveled very well. That is the backstory. Glenn came by in first week of October on a Friday and spent a good amount of time with me testing and going over where exactly the sound was coming from. we discussed my needs to dampen the sound as much as possible within the confines of my budget. He send me an itemized description of all the work he intended to do that evening and explained the reasons why it would help my situation. It was within my budget as well. I had two other sound specialists come by for an estimate and Glenn was by far the most astute and detailed of the three. In terms of cost they were all comparable. For the same price, it was obvious Glenn was the right choice. we schedule the work for the 3rd week of October, estimating it would take 4-5 days. It took 6 days which is totally fine. There were some logistics issue the second day where they just fell short of needed materials so had to close early. and the last day was the "fit and finish" clean up day. basically, it was within time and no issues there. as far as the work goes, on a base level they did exactly as what they said they would do. Sound was reduced by probably 75% or more!! Great! on top of that, demo and construction is dirty and dusty work. Glenn's team (giving some props to Kenny) cleaned up daily and was very respectful of the house. All in all, they did a great job. To be fair and balanced, was there anything i did not like? to be honest not really. I was very happy with the work. I felt I got my money's worth in effort, build and quality. Glenn did as he said he would and was very receptive to all my questions and concerns through the process. Would i recommend Glen and Total Home Interiors to my mom or my sister? the answer is Yes. I rely on other people's reviews, I hope this will help you in your decision making process. Regards, Paul"

"I purchased a multifamily house with 2 stories. The 2nd floor had 1 inch original hardwood from 1920 that laid on the floor joists so you could hear every footstep downstairs and my tenants almost moved out. I hired Cesar to take on a tedious and technical ceiling soundproofing technique for the apartment using RSCI rubber clips, hat channels, insulation, and making the 1st floor airtight. I was so impressed with how he was able to juggle handling my tenant for 2 weeks, compensating for delayed shipping by driving 3 hours to New York and picking up the materials himself to make sure we meet the deadline, redoing 1 entire room at his loss and not charging me for it because the original technique we tried did not work, and listening and working with me to make sure we didn't miss any details that would cause sound transfer (and this was impressive because I am very detail oriented). My tenants moved in and were very impressed by the finished looked of the new ceilings and crown molding. We saw a sound improvement of about 15 STC in both airborne and impact noise. It cut down sound transfer by 2/3 in the 1st floor apartment. I will be adding rubber underlayment upstairs underneath the new flooring to completely block out the rest of the impact noise that transfers from the floor above to the walls downstairs that support it! I'll be calling Cesar and his crew again."

"It went well. Was $1,750 for taking out the insulation and putting the blown-in cellulose insulation in. They were quick and it only took them about 2 hours. The workers didn't know that the present insulation was to be taken out. It wasn't on the contract, but the salesperson should have communicated that to the workers. Once I explained that that is what the salesperson said would happen, they were OK with doing it. The company owner did not show up on the day of the project. Other than those 2 things, I think they did a good job."

FAQs for insulation service projects in Castle Point, NJ

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.
