"Very well, these guys are great, they seal everything right and load tons of insulation. My house is now at a R60. And this was not cheap, however I do not expect heating costs to go down for many years to come unless we all go solar."
"I could not be more impressed with Jesse and his team. They were so responsive, so professional, and so incredibly helpful. Great communication throughout. Great work product. Pricing that was very competative and reasonable. The next time I have an insulation need I won't even both to get bids from other shops. I will just use Century. Highly recomend."
"Ed and his crew were awesome to work with. He called back within minutes and we had his bid an hour or two later. After 4 other bids we ultimately went with Ed because he helps his crew on the roof. They do excellent work and the clean-up was great too. Roof was done in two days. Highly recommend Ed."
Trevor was part of the team when we were finishing a kitchen remodel in 2014. At that time we had him open a space in a wall for a future cabinet, but not cut through the wall until we knew what we wanted. We figured out what would work best and asked him to finish the wall cut-out and smooth the sides so the new cabinet will fit. While Trevor cut the drywall, his helper vacuumed up all the dust. They also moved a storage unit to another room. Trevor also answered some questions I had about a problem outside.
They were done with everything within 40 min and no dust or drywall fragments remained. I'm sure he will return to help with some other job in the future.
"As always, we are thrilled with the work done by Hoffman Weber Construction. Love the look of the windows - but also the safety factor. The installers were on time, friendly, and did a super job. We would hire them for any of their services."
"Mark was very prompt with the inspection and bid, and was able to get right to work. He sized up my situation expertly and suggested details that I would have overlooked. His crew of two were very efficient and finished the job in five hours. Mark was present for the start and finish of the job. He had excellent advice for a future phase of my project, and was open to doing those parts of it that are beyond my expertise. (In other words, he can work small and not insist on taking the whole job). Affable guy too, with an enthusiasm for insulation. Recommended. "
"Damien and his crew are fantastic! I highly recommend them for any and all of your construction needs. I am a picky interior designer, and they surpassed my expectations! They went above and beyond to recommend other subcontractors and talked through everything with me thoroughly throughout the project. They worked quickly, always cleaned up at the end of each task and were friendly, punctual and very easy to communicate with by phone and email.
Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.
You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.
However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.
Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.
DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.
On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs$1,825 to install throughout the typical home.
