Sureseal Windows was established in 1995 by Darren Melia.

Darren had managed two companies involved in double glazed UPVC products.
The company that Darren previously managed decided to pull out of the domestic sales market in order to concentrate on trade and commercial areas. Darren decided that this was the right time to set up his own operation and offer a sales and installation service.

Sureseal has grown from a small local company based in offices within Liverpool City Centre to become one of the biggest suppliers of UPVC products in the Northwest of England. We now operate from two main offices in Liverpool that look after distribution nationwide. We now install all over the Northwest and supply windows as far afield as Aberdeen and Portsmouth using TNT and other distribution companies.

We have found that by keeping our cost low and our service high we get a lot of recommendation and repeat business. In other words “customers join us for the cost and stay for the service”.

The year 2000 saw us move into the commercial market and has seen a massive growth in this sector.
