About Us

A Local company with a national, award winning reputation for quality right across the board.  Chatsworth Windows started out in 2000 and has experienced huge growth, year on year.

This is due to our ongoing commitment to product development and customer service.  We don’t claim to offer the cheapest products.  We do, however, claim to offer the best value for money.  This is why we are the biggest and most recommended double glazing company in the area with over 20,000 happy customers.

FENSA registered, and an IWA (Independent Warranties Association) member.  How many other companies can offer this level of reassurance that the products and services offered are of the highest standard possible?

In-house manufacture.  Chatsworth are the largest manufacturer in the area and the only manufacturer in Northallerton.  By manufacturing our own products we maintain total control over quality and efficiency.  Also, all of our hardware is ‘suited’, so all handles, letterboxes, numerals, knockers and hinges match.

NVQ qualified fabricators and installers.  Highly experienced personnel, utilising state of the art machinery and techniques; ensuring beautifully crafted products, fitted with attention to detail and pride in the finished article.  Every installation has a qualified surveyor on site.

£10 million Public Liability Insurance (we want your house to be covered while we are working there).

Our finance packages are underwritten by Barclays Bank, a High Street lender as well as a household name.  We are licensed credit brokers.

The latest technology, multi-point locking systems.  Every opening sash comprises up to 10 individual locking points, controlled smoothly via a single handle.  All our door locks are made by Yale, the very best on the market.

Tested to BS7950 for weatherproofing and enhanced security.  Products tested to this level assure the customer of the best defence from extreme weather and intruder attack.

70mm Multi-chambered profile incorporating 3mm walls.  Our PVCu sections comprise multiple chambers.  The chambers trap air and dramatically increase the strength, durability and thermal efficiency of our windows and doors.

EPDM welded seals and gaskets.  Rubber is comprised of a natural product that, by its very nature shrinks over time and leaves black marks on windows.  EPDM is a synthetic product, and combined with modern extrusion methods ensure no shrinkage or perishing, making your windows and doors draught-free for years to come.Fully reinforced to REHAUTM Specification.  Where required, steel sections are inserted and anchored into the frames, adding strength and rigidity to the finished product.

Virgin Plastic.  REHAU PVCu does not contain recycled plastic and is pigmented with Titanium Dioxide, a completely neutral product that gives a long lasting brilliant white finish, guaranteed against discoloration.  It is also BBA Approved (a European standard of excellence in building materials), meaning a minimum life expectancy of 25 years.

Energy rating and carbon footprint are becoming bigger and bigger concerns for many people. Chatsworth windows offer 2 levels of energy efficiency,  ‘C’ and ‘A’ rating.  Our ‘A’ rated windows are actually accredited with a certificate from the B.F.R.C. (British Fenestration Ratings Council). Other companies may sell a ‘compliant’ product which is NOT ‘A’ rated.  Beware!

10 Year Insurance-Backed Guarantee as standard.  Be assured that the guarantees we offer are genuine and offer real peace of mind.

One final point:-  Whilst you live at the installation address, we will guarantee your sealed units against misting-up between panes...FOREVER!
