From the Forum – Attic Insulation and Deck Renovation Recommendations

Blown in Attic Insulation Recommendations:

“I need to add insulation to the my attic of my row house. The attic space gets lower as you get closer to back of the house. I am having trouble finding someone that will do the work because the height in the back (or lack there of). 3 Contractors have come by but said they will not do it. Has anyone had luck finding a contractor to do this work when the attic space gets lower on one end? I think there is about 3 feet in the lowest part.
Thanks for any help!”

Deck renovation:

“I’m looking at tearing down my rusty, steel backyard deck and replacing it with a wooden deck. Anyone done something similar to remove/add a (small) deck? Any advice on possible contractors and cost estimates would be appreciated!”

  • Rent a blower from Lowes, crawl into your crawl space and do it yourself.

  • I had my rowhouse attic insulated not long ago, including the tight crawlspace in the back. Used Dan Roberson. He is really great and has guys that can get back there.

    It made so much difference in the winter and especially the air temp quality in the house this summer.

    • I had Dan do my attic a few weeks ago too. On time, beautiful work. I am very pleased. He air sealed as well as blowing in fiberglass.

      • To the commenters who recommend Dan Roberson: would you mind telling how much it cost you to have your attic insulated? A per sq foot number is fine if you dont want to say a grand total. On average, what was the difference you saw in your heating/cooling bills? And is the blown-in material the better way to go?

        Sorry for all of the questions… just moved into our first home and one of the recommendations in our inspection report was to have more insulation added to the attic.

        • Same – would love to know how much for a rowhouse.

          • I have a ~1000 sq ft rowhouse, ~500 sq ft attic with very limited attic access. Blown-in, to basically fill the attic space, for about $2500.

            FYI — DC also has a program through DC SEU and does rebates for insulation. I’m in the process for that but wanted comparisons so got the quote from Dan & Co

            Quality Insulation is likely better at what they do, but 50% back from DC is pretty substantial.

        • I don’t have my square ft info but Dan at Quality Insulation charged us $1500 for air sealing, and blown-in fiber and something else I’m forgetting. They came on time, finished pretty much when he said they would (a little over 2 hours) and there was no mess left at all.

  • For the attic insulation there are two things that I strongly recommend. 1) Use an insulation contractor rather than a GC. The reason is that they buy their materials in bulk and get them way cheaper. I paid less for sprayfoam from an insulation company than my GC would have charged me for fiberglass. 2) Don’t use fiberglass, which is not good and can cause serious health problems. Other materials are much better, safer, and longer lasting. Sprayfoam is the best (thickness to insulation ratio) but is very expensive. Cellulose is very cheap, safe, and good, but the two disadvantages are that you need a lot of it, about 17″ sprayed down, and it will make it hard or messy to access that space in the future for things like recessed lighting, etc. I went with both in different parts of the attic. I used AAA Insulation, I think, and they did a great job and gave me a good deal. I think I also found a discount for them on Angie’s List, but that was three years ago.

  • I used Elysian Energy and was very satisfied. They did a lot – attic insulation, insulating the ceiling of an addition, replacing very old duct insulation, sealing the ducts from the inside, etc. It paid off this winter and has been especially good this summer. It took a while to nail down the scope of work with them but I think that’s because we had so much to do. They also came back after they did the job to fix one thing that wasn’t really their fault, and they didn’t charge me for labor.
