Our service department will do everything they can to make sure the customer is satisfied before and after their purchase. We use the strongest and most durable products on the market, and that is why we can offer a 20 year to lifetime warranty on all our eavestroughs. And our Leaf Solution product is the only eavestrough guard with a money-back guarantee against clogging. We offer such competitive pricing that if a competitor gives you a better price we won’t only match it, we’ll beat it!

Sentry Exteriors is always looking for new ideas to make our business better and our customers happy. We want our customers to know we care about the environment. All the old eavestroughs we take off your home are recycled, never taken to a landfill site. We even recycle all the scrap pieces that are created from new jobs. Sentry Exteriors is really excited to now offer Rain Recycling Systems. Why not use your rain water for watering the lawn or garden and help to make a difference by going green.
