The Durability of Insulated Vinyl Siding

Conventional siding is hollow and can be damaged by rain hail or even a flying baseball. Insulated vinyl siding can give five times more impact resistance over hollow type siding. Insulated vinyl siding also comes in an array of colors and it requires very little or no maintenance at all.

Insulated siding is better at protecting against weather elements and sounds than traditional siding is. It is also made with a rigid foam backing which can wield a straighter and cleaner exterior appearance and allows the material to lay flat.

It went very well. I live in an old home where nothing seems to be quite square but the new door fits (seals) perfectly. I asked that they preserve the interior molding as we wouldn’t be able to match it and they did. There was one piece of sill on the floor that I wasn’t happy with, so we chatted about what I wanted and they replaced the wooden one with a metal one to match the door hardware.

There was a follow-up call to make sure that it was all done well. I’m know that I could have gotten a door more cheaply, but I would not have gotten the quality of materials or the quality of install.

Description of work: I needed a new front door.

The crew of two men did an excellent job; in just a few hours, the new windows were in! I didn’t realize what an extensive job it was; they had to remove the wood trim from the window frames to insulate the interior, install the windows, and replace and caulk the molding; I’m amazed they did it all so quickly. Everything was cleaned up and the windows look great. The job went so well that I’m having them back to replace four more leaking old windows.

Description of work: I had 6 double hung windows replaced.

I cannot say enough good things about O’Sullivan Installs. If you’re looking for someone to install siding/windows/doors in your home, look no further! When I started shopping around for estimates for my project, I reached out to several local companies. O’Sullivan sent their man, Brian, out to my house for a very detailed and thorough presentation that went through all of the options available, a comparison of the materials they use versus other companies and why they’re better, including a cost comparison. The attention to detail there was what easily won me over.

O’Sullivan goes above and beyond when it comes to the little things – for example, once they strip the old siding off of the house they treat it with mold and insect repellent as an added step before putting the new wrap and siding on. Their crews are also certified to perform the warranty work for any material issues that you may encounter for the duration of the warranty which prevents a lot of the runaround you’d experience with other companies who would tell you to contact the manufacturer of the siding instead. They even bring their own porta-john to the job site so that you don’t have to worry about their crew making multiple trips to your bathroom while they’re working. Once the job was scheduled to start the supervisor, Mark, stopped by to do a walkthru with me to go over what would be done, identify any areas that may pose an issue or obstruction (for example I had a shed that needed to be moved away from the house so that the siding could be installed.

I emptied it out and Mark had his crew help me move it over a foot or two so they had room to work) and to check and see if I had any questions. Mark would also come by just about everyday to check on the progress and quality of the work and answer any questions or concerns I might have had (I had no concerns). The crew was very professional and polite throughout the install process. You could tell they worked hard and took pride in the quality of their work and they were FAST! My project was done in about 6 days (granted, I have a smaller, squared off house, but it was still impressive). They made sure they cleaned up at the end of every day and were especially thorough when they were inside the house for the window installs. They installed new doorbells and light fixtures for me at the end of the job as well which was great. Once the job was finished, Mark gave me a day to sort of kick the tires and test all the new windows and doors to make sure I was happy and if I found any issues. I did find a couple of small items that I brought up with him and he had them resolved for me the next day. He even offered to come back if I ended up doing any work on my deck or anywhere else that may touch the siding and might need a little tweeking. Again, I can’t say enough good things about this company. They set the bar very high and knocked it out of the park. I highly recommend O’Sullivan Installs for all your siding/window/door needs.

Description of work: All new insulated vinyl siding, 8 new replacement windows, and a new front entrance door and storm door. Also, fascia, soffit, gutters and downspouts.
