Welcome to Lewington & Son

At Last, a double glazing windows, doors and conservatory company that offer a 100% Insurance Backed 10 Year Guarantee on all parts and Labour!

The double glazing windows, doors and conservatories business is very competitive, everyone is trying to cuts costs and still make the most money that they can to stay in business. And as you know, when they come to cut costs the first people to suffer is the customer.

Many double glazing companies start off by sourcing their products from cheaper suppliers in the market. Poor quality generally means more things that will go wrong. These companies also cut corners when they fit and worst of all they only guarantee you for parts, not service, and we all know that it is the service that costs the money.

The most concerning thing in all this is that the guarantee that they give you is not insurance backed. That means that should the company run into financial difficulty and you need replacements for your doors, windows or conservatory then you may have to pay another company to fix or replace it. That can be expensive.

Lewington & Son offer a breath of honesty, reliability and a 10 year insurance backed guarantee. And the reason why we can offer such security and reliability is because we use high quality components every time.

Sure you want to save money and have a competitive quote, and here at Lewington & Son we can offer you both a competitive quote AND an insurance backed 10 year guarantee on parts AND labour.

At Lewington & Son we offer a 100% 10 year guarantee on parts AND labour. And as you may know it is the labour costs that can escalate if you do need things fixed or changed. We know of no other company in our area that will offer you this type of reassurance.

In addition to our 100% guarantee we also pride ourselves on only stocking top quality products which are secure, look good and build to last.
