Common DIY Insulation Mistakes - Vermont Foam Insulation

Installing new attic insulation or crawlspace insulation has a lot of benefits for your home, from better comfort to lower heating and cooling costs. In order to get all the benefits of a home insulation upgrade, however, it needs to be done right.

Insulation installation, especially spray foam insulation installation, is a skill that takes a lot of training and experience to learn. Without the help of a professional spray foam insulation contractor, it’s easy to make expensive and even dangerous mistakes.

Vermont Foam Insulation has been installing insulation since 2006, and we’ve fixed plenty of DIY home improvement projects gone wrong over the years. Here are some of the most common DIY insulation mistakes we see among homeowners in Lebanon, Hanover, Enfield, and the surrounding areas.

1. Using the Wrong Insulation Material

The first step in any insulation installation is choosing the right material. Different homes, and different areas within the home, require different materials. Most DIY insulation installers end up using fiberglass batts because they’re affordable and can be found at just about any hardware store. But fiberglass batt insulation is not usually the best choice. A professional insulation company will be able to recommend the right material based on your home and climate.

2. Not Air Sealing

Air sealing is one of the most important steps in the attic insulation process. Air sealing stops air from moving between your conditioned and unconditioned living spaces. This keeps hot air, moisture, and outdoor air pollutants from entering your home.

If you insulate without air sealing, air and moisture will not only come into your home, but they’ll also move through your insulation, damaging the material and making it perform worse. Once the insulation is wet, dirty, or moldy, it will have to be replaced.

3. Overstuffing

When you’re installing home insulation, you might think the more the better, right? But that isn’t always the case. You need to make sure you have enough insulation, but you don’t want to overstuff.

If you jam fiberglass batts into all the nooks and crannies in your attic, you’ll end up compressing the material. This makes it impossible for the insulation to work properly.

4. Not Using Enough Insulation

Not installing enough material is one of the most common problems we see with DIY insulation installation. To make sure you have the right amount of insulation, you need to take precise measurements and make sure the insulation is the right thickness to meet R-value recommendations in your climate zone. A professional insulation company will know how much insulation you need based on factors like your home’s size and location.

5. Trying to Install DIY Spray Foam Insulation

Spray foam insulation is one of the most effective insulation materials. It acts as an air sealant, an insulator, and a moisture barrier all in one. But installing spray foam insulation without the proper safety equipment and training is extremely dangerous. If you want to install spray foam insulation in your attic, you need to hire a professional spray foam insulation company.

Thank you so much for “foaming” us. We are blown away by the incredible work. Your crew was equally kind and personable. We look forward to working with you again and will be showing our family our Foam Home at Thanksgiving. Thanks again

Btw, it’s simply amazing what a difference the basement insulation has made already. This morning I walked barefoot from the kitchen (over uninsulated crawlspace–always has a cold floor) into the dining room. The difference in floor temperature was startling. The dining room floor literally felt as though it had radiant heat installed, it was that warm. My poor basement freezer–it used to have such an easy time staying cold. Now it will have to struggle against tropical conditions! Thanks, Jonathan

VFI did an insulation job for me last year in Wallingford, VT. Just have to say. WOW! What a difference! For the first time since we have owned the house the thermostat actually gets to the set temperature. We estimate we will save about $2600 on our heating bill alone this year! That is a 65% savings over the previous heating seasons. Obviously there was virtually zero insulation in the walls and what was installed was installed incorrectly. Just have to say thanks again and if you guys ever need a referral, I’m happy to supply one any time one is needed! Warmest Regards, Scott (and Wendy)

Happy New Year to you both! Buddy and I just wanted to give you an update on our home since we had the insulation installed last summer. We are VERY pleased with how cozy the house is and are constantly amazed at the evenness of the temperature. We have noticed a marked decline in the amount of wood we are burning (compared to last year) and we don’t think the oil burner has kicked on once by itself. We typically wake up to a house that is 70 degrees, even though the wood fire had long since died down!! So….if you would like to use us as a reference we would be happy to share our experience with any of your prospective customers. Trust us…we will have nothing but good things to say!! Thank you and best for the New Year! Lynn & Buddy

I can’t believe how warm the bathroom on the new master side is and the powder room on the front of the house. What a difference! Thanks so much for your patience and hand holding throughout the process. The guys were hard working and respectful and a pleasure.

VT Foam wrote up a quote on the spot, did a test on my building, came back to spray exactly when they said they would, did terrific prep work, cleaned up after, ran a new test on the building and submitted (via electronic download) paperwork to Efficiency Vermont – ALL in a seamless, professional manner! I could not have asked for a better company to do the work!

…We’ve been uncertain how we’ll insulate the pony wall and the eaves, and had been considering wool insulation, regular fiberglass insulation, and blown cellulose. Now, Will is here to check out the house and tell us what he thinks about it being a candidate for foam. Will works at Vermont Foam Insulation We are sold on his close cell foam when he tells us that at an R-value of 6.5 per square inch, we’ll get great insulation using just 3-4 inches of the stuff. We’re even more sold when he tells us that his team is doing a job just ten minutes down the road, and he thinks they’re overstaffed. He could send a guy over to do the job in just an hour! Will is as good as his word. Less than an hour after he leaves, a friendly man arrives with a big truck and a long hose and a full-body protective suit. In under an hour, we have a fully insulated home.

The installers were very professional and check the work site over before starting. They explained the entire process and did a great job of covering area of our basement so they would not get any insulation on them during the spraying process.

Your professional work at my home lead me to recommend Vermont Foam for the total insulation of the new addition at our church. We are very pleased with the quality of the work.

I waited until the coldest part of winter was over before giving this review. Improvement in heating and comfort was amazing. We no longer have 8 – 10 foot icicles on the back roof. The previous year the icicles were so large that when they crashed down they broke the deck railing. We will have them back hopefully this year to do the other side of the house as their work was a retrofit and this time some partial walls will have to be opened to complete the foam installation. The saddest part about this is that this is not an old home but rather was built in 2006 with up to code fiberglass batting insulation which was done by the builder. if I were to build new I would without a doubt use foam insulation as there is no comparison to fiberglass batting and plastic wrap. I was also on site when they were doing the removal of old batting and installation, I was worried that the foam spray would make a mess of the house but they used plastic-wrapped barriers and layed down floor protectors wherever they walked, and were super professional and courteous especially since this is such a hard job.

I waited to write a review until the winter set in so I could really test my new insulation. President’s weekend 2016 (record cold -20 degrees at my house in Weston), and my great room was toasty warm ! I am really pleased I invested in the foam — thank you very much for your help, and great product!

Excellent job on my basement and crawl space in Newport NH. I was so satisfied, I will be also using Vermont Foam Insulation at my home in Gilsum NH in a few months.

Mike B.

Vermont Foam was on time, was in and out more quickly than I expected and did a great job. They had very little over spray, and cleaned up well. I would use them again if I had more foaming.

Charles H.

Shaftsbury, VT

Amazing workmanship and so timely. House is so much warmer. Customer service was impeccable. Highly recommend.

Shea S.

Londonderry, VT

VFI did a great job at my house. We had an old drafty stone-walled basement – full height and crawlspaces. VFI covered the dirt-floored crawlspaces with a heavy-duty plastic we had found & foamed the basement walls from the sills down to the plastic vapor barrier. Made a huge difference. Where they foamed the stone walls – that solved a long-standing water penetration issue, and even brightened up the basement. Customer service was great. The crew was very professional and left the place clean as a whistle. I highly recommend VFI.

Jim S.

Dorset, VT

Great service and work!

Lois C.

Solid crew and quality work. I had them do work to a vacation home and was not there to supervise. Everything was done right the first time.

Jeffery T.

Barnard, VT

We have a house built in 1776. We had Vermont Foam do our basement and it helped keep our place much warmer in the winter. Gone were all the chilly drafts. And we burned 40% less fuel oil last winter. I heartily recommend Vt Foam Insulation.

Eric T.

Chester, VT

Your crew did a fantastic job insulating our re model job. Everyone worked hard,kept the job neat, and did some hard crawl space work without a single complaint! Would recommend your company to anyone that asked me, and will have you back on any job I need insulation work. Thank you!

Douglas H.

Townshend, VT

I can’t tell you how pleased we are with the outcome of that huge roof project this Fall. It might have seemed a foolish expense and a waste to replace all those nice old boards and shingles, to end up with a roof that looked just the same as it did before. We tried blown-in insulation 10 or more years ago, and that didn’t work. But now, after 40 years – and probably lots longer – for the first time we’ve had a heavy snow cover, and cold weather, but lo and behold, no icicles on the front of the house, no damp spots inside, or ice running down the front wall of the house! Thank you for your good work. Tim & Kay

Tim & Kay

West Chesterfield, NH

Pretty incredible. Insulating the walls of our crawl space and taping up the vapor barrier was the definite right choice The crawl space has stayed a pleasant and steady 48-50 degrees over the past few months and even has persisted at this level throughout this cold snap when it was 22 below zero outdoors!!! And, the Humidity has hovered at a very respectable 50% or less. And our floors are noticeably warmer And our electric bills are down WHAT CAN I SAY!! Thanks!

Joan & Barry R.

Winhall, VT

It’s been a pleasure working with you and your guys. Matt and Chris did a fantastic job. They were friendly, courteous, professional, and left the place clean and ready for our next phases. I’ve had some less-than-stellar experiences with insulators in the past, but your company has far exceeded all of my expectations on all fronts. We will absolutely be calling you for any and all of our future projects. Thanks again for everything!

Chris

Arlington, VT

As far as our dealings with Vermont Foam Insulation are concerned – they were good (very good). Essentially after 18 years spending winters in Florida we realized that the old “moused-up” fiberglass insulation in both attic space and crawl space (we don’t have a regular basement) should be replaced if we were to spend winters in our house again. After looking over our situation VFI agreed that we were definitely candidates for foam insulation and that having it eould make a very definite difference in keeping our winter space warm and reducing propane consumption and indeed it has. Your fellas completed what seemed to us a pretty miserable task, quickly and very efficiently, leaving everything very clean.
