About Us

Sealtight Windows has built a reputation for providing outstanding quality products, fantastic customer service and a guarantee that cannot be beaten. Established over 20 years ago, our family owned business has been manufacturing and installing high quality UPVC windows, doors and conservatories across Teesside and the surrounding area.

Over the last two years we have invested heavily in a new showroom which showcases the full range of our products, including our unique Traditional Orangery, our bespoke Conservatories, and our range of Solidor Composite doors.

So why should you choose Sealtight Windows?

We know that we have to be different and offer something that our competitors don’t. We truly believe that this lies in both our approach to new customers, and the standard of aftercare that we provide. Arranging an appointment with us, will give you the opportunity to discuss how best to achieve the outcome you desire. In pricing for the work you require, we are unique in that we believe in a no-pressure sale, and we offer One Price and One Price Only.

We don’t quote unrealistic figures, only to discount it to try and persuade you to go ahead. We leave that nonsense to our competitors. There is no pressure to buy with Sealtight Windows, and once the appointment is finished, you will be left with a quotation which is valid for 30 days, allowing you time to consider our proposal. We do not contact you after that appointment, as we believe in the quality of our products and service, so we have no reason to pressure you into a sale.

If you do decide that Sealtight Windows is right for you, then you will also benefit from the fact that we don’t ask for any upfront deposit payment. We want all of our customers to be reassured that all of the work will be completed to our usual high standards, and with the minimum of inconvenience. This is why the majority of our new customers come via recommendation from existing customers who were so happy with our approach.

Finally, we want our customers to be assured that our written guarantees are actually worth the paper they are written on. That’s why we encourage you to visit our Factory and Showroom. There, you will see all of our high quality products on display, and we can answer any questions you may have. You will only ever deal with Keith (Owner and Managing Director), Richard (General Manager) or Brian (Sales Manager). We want our customers to know that they can speak to us whenever they want, and we are available in the factory and showroom all day every day. Sealtight Windows is a truly family run business and we want all of our customers to feel part of the Sealtight family.
