They installed our roof in 2019. They did not come on the day that they were supposed to and did not call to tell us. Ended up coming a few days later. Gutter was installed over an outdoor light instead of along the edge of the house... it functions but looks very stupid and will bother me until we hire someone to fix it one day. Held off on writing a bad review until now when my roof has started to leak along our chimney. Called to have them come take a look since there is a warranty. It’s been... Read more

We received three bids for replacing the siding on our house. We chose Coastal not only for their competitive price but were impressed by the experience and knowledge of representatives Terry O'Connor and Tim Allcott. As the project is still underway, we look forward to working with Terry and Tim and the crew at Coastal. Can't wait to see our 100 yr old house become new again!

My windows are not installed as of yet, but my experience with both Terry O'Connor and Tim Alcott were great. Both were professional, friendly and very knowledgeable. Also, both were very clear in explaining the process, cost, window warranties and timeline. I'm very happy with my purchase and I can't wait to see my new windows!!!!.

We called Coastal Windows & Exteriors to replace the siding and some windows on our house. Tim and Terry were here on time and prepared. They went over all the options and explained every detail. They are knowledgeable, patient and easy to talk to. Tim and Terry are a great representation of the company. We are waiting for the install and I'm sure that will go just as smoothly as the consultation did. I can't wait for our new look!

Terry O'Connor and Tim Allcott have been great to work with. They came up from Mass to Derry, NH to meet with us and were very thorough in providing us with lots of options on siding and the associated prices on the spot. We have emailed them with a few changes and they respond right away. We are due to have our siding installed in about a week and I suspect with all the positive feedback we have seen online, and our interaction so far, that we will continue to be impressed with the compan...
