Why should you have your home insulated with vinyl siding?

Are you hoping for a way to improve the functionVinyl Siding Installation installed on a complex in Haverhill MA and look of your home on the exterior at an affordable rate? If so, you will see the vinyl siding is the top exterior cladding across the United States. When considering that the leakage of air can account for about 30% of the heating and cooling energy costs in Massachusetts, insulated vinyl siding will give you a very obvious solution.

The purpose of insulated vinyl siding is to cut back on energy consumption, increase the value of insulation for the wall system and improve the curb appeal and stability of the siding. Additionally, the insulated vinyl siding will serve as a wonderful noise barrier to external noises.


Insulated Vinyl Siding Durability

Unlike your conventional hollow siding that can be damaged by the elements, or even a stray baseball, the insulated vinyl siding will be five times more resistant to impact over hollow siding options. Insulated vinyl siding will come in a range of colors and it requires very little, or no maintenance at all.

It will also be higher in weather performance and offer better sound control than traditional siding. The insulated vinyl siding is made with a backing of rigid foam that can give you a much straighter, cleaner exterior while allowing the material to lay nice and flat.

Tim, Arturo and their crew were absolutely great. Tim kept in touch, answered all my questions, gave me an accurate start date and checked in frequently in person and by phone as the job was being done.

Arturo and the rest of the crew were friendly, polite and professional. They worked long days and did the whole job from start to finish with no disappearances or other commitments. (My neighbor coincidentally hired someone to do vinyl siding on his house at the same time I was having mine done – his house was started a week and a half before mine – one side of the house done, installer disappeared for a week, did part of another side, etc. – six weeks later, the job is still not done.)

O’Sullivan Install’s work looks perfect and they even finished two days ahead of when they originally told me they’d be done. A couple of days after they finished I found a can of touch-up paint on the front porch that Tim had dropped off. I couldn’t be happier with the work they did and I highly recommend them.

Description of work: Old aluminum siding and shingle removed and new siding installed.

After contacting O’Sullivan Installs about an estimate to replace all the windows in my brownstone condo, I met with George Williams who is the sales representative. George looked at the current windows and asked what type of replacements I was looking for. He showed me the different types of replacement windows that O’Sullivan Installs uses and developed installation cost estimates for each type of window on the same day.

George answered all my questions and there was not any high pressure sales pitch. Once I chose O’Sullivan Installs, George and Tim O’Sullivan (the owner) came over to finalize the paperwork and take final measurements. Tim took care of all the necessary permits with the town which included review and approval by the town’s preservation committee (extra effort on his part since I was not aware that the window replacement needed preservation committee approval). Tim kept me informed throughout the permitting process.

Installation took three days as there are always complications that come up in a building that’s over 100 years old. Tim and his crew were great and kept me informed every day. Their work was very detailed and thorough. Extra kudos to them for having to carry really big windows around the block and up a couple of flight of stairs (that’s what happens when you don’t have reserve parking in front).

They also took care of disposing of the old windows and cleaned up every day.
Tim and I did a final walk through to make sure everything was completed and to my satisfaction. It was a very professional operation from start to finish. The price was fair and the quality of the work was excellent. I would highly recommend O’Sullivan Installs for future work.

They were very flexible in scheduling the estimate and provided me the estimated cost at the conclusion of the walk around. Once I accepted the estimate the approximate start date was five weeks. However because my job butted up against another interior door installation job they asked to move the date up about 4 weeks. I was glad to do this.

The job took about three days and Tim and his crew were extremely conscientious about asking me about my preferences and then working to meet them without push back or haggling. One aspect of the job was converting an interior double slider to a French Door.

Because of the construction of the house half of the install time was spent performing this replacement. However they took the time and care to make it come out right and I was extremely pleased with the final quality of the work. Also, some of the doors jams were out of square. They had quite a bit of experience efficiently squaring the frames rather than chopping corner from the new slabs. Excellent work.

Description of work: Replaced 12 interior luan doors with solid core six panel wood doors slabs.
