"They did a whole rebuild in one day , I had 4to 7ft of blow foam On each wall and ceiling of my attic they tore it out and put a whole New roof plus ventilation in a day! I was so impressed they were kind they even patched where my roof was leaking since my apt was a week or so out. I worked with Micheal Benaquist who was absolutely phenomenal. He made me feel safe and secure and was knowledgeable on any questions I asked. From financial options to helping me understand the roofing materials. I would recommend them to anyone. They are worth the extra few bucks!!!"

"They weren't too bad but I think they could have done a better job. They did a couple of different jobs. I own rental property but all the 3 buildings are on the same piece of property where I live at. So far it seems they've done the trick as far as solving problems like pipes freezing out, that kind of stuff. Unfortunately my house itself can't be insulated any more than it already is but what I was trying to get at, like trying to get rid of dross and making sure that doors seal up well, things like that, I think they could have done a little bit better. If their prices are as reasonable as right now, I'd probably use them again. They could have tried harder to insulate my apartment. There are places they could have done it because we had a section of the house redone. Our kitchen was remodeled and they could have done it but they didn't. They could have been more attentive to detail. My house is not a new house but its also not a real old house either, it was built in the 40's so something needed to be looked at to make sure that the draft was kept out not just from the windows and walls that were insulated but also the door, the door jambs, making sure the door fits tight and all that kind of thing."

"Mark was very professional and gave a complete explanation of the estimate and work involved. while only one man showed up on the date scheduled for insulation, he completed the exterior walls foam insulation work including the interior basement rim in the day as promised and was very courteous and thorough. I have noticed quite an improvement in the warmth of my home and especially since we have had 2 very cold weeks since Christmas. negative degrees! I am very pleased with the company and the work."

"Upon inspection, the tech would give us information that would decrease the probability of pests.  One example is that we should get rid of the peony plants on the side of the house as they attract ants.  He also notified us of some damage to our roof that could allow water to seep in (which in turn would attract bugs)

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

"The job was completed in a timely manner and exceeded my expectations. I was planning to apply two coats of spackling myself, but it only needed one coat saving me time. I also got good advise for techniques to make my job easy. I would hire them again for any drywall work or other home improvements for that matter."

Drywall Insulation FAQs, answered by experts

Although they have similar applications, spackle and joint compound are not the same. Their primary differences lie in their composition, consistency, and ideal use cases.

Spackle is composed of gypsum and binding agents, making it thicker than joint compound. It dries quickly and is easy to sand, which makes it ideal for small wall repair projects like filling nail holes or patching minor damage.

Joint compound, also known as drywall mud, consists of limestone and gypsum. It is primarily used for large-scale projects, such as taping and finishing the seams on newly installed drywall. It tends to shrink more than spackle and can be more difficult to spread.

While both products can be used to fill small depressions and cracks, spackle cannot replace joint compound for taping and mudding new drywall. Conversely, you can often use joint compound for small patching jobs typically done with spackle.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Whether a drywall anchor can be reused depends on its material, type, and the method of removal. Plastic anchors, including expansion and self-drilling types, are generally designed for single use as they tend to break or deform upon removal. Metal anchors, such as toggle bolts, are more durable and may be reusable if they are not damaged during extraction. However, with toggle bolts, the toggle piece can fall into the wall cavity when the bolt is removed, making it difficult to retrieve. If an anchor is damaged during removal, for instance by having its head cut off, it cannot be reused regardless of the material.

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

Yes, professionals often repair minor wall openings made for insulation injection to restore the surface.
