About Three Counties - Triple Glazing Benefits

Accredited Double Glazing: Quality Products

From 1st July 2013 it became mandatory for manufacturers of windows & doors to apply CE Marking to their products. CE marking indicates that a product conforms to legal requirements in specific European technical standards known as harmonised European Norms (‘hEN’). It enables a product to be placed legally on the market in any European member state. However, regulatory requirements may differ from country to country.

Our Declaration of Performance

A key part of the CE Marking process is that a Declaration of Performance must be produced by the window manufacturer. The Declaration of Performance details all of the essential characteristics of the product and enables the information to be available to the end user. The document has to be available in the public domain, so not only does the certification need to accompany the product it needs to be visible in places such as our website. For a comprehensive list of all our product DoP's (declaration of performance please click here.

We used Three Counties to replace our front door and porch. Throughout the process, from design, quote, survey and installation the service and level of communication has been fantastic from all involved. The installation team were great, friendly and courteous, working cleanly and tidying up after themselves. We would have no hesitation using Three Counties again, or recommending their services.

Fantastic service from start to finish. Kept me upto date all the way through the process. Very prompt coming out to measure up and discussing what windows I would like. The install was done professionally by a fab team (James and Josh), cleaned and tidied as they went, friendly team. Would highly recommend

Very happy with Three Counties. That’s the second time we have ordered services from this company and both times it was flawless. Prices are very competitive, customer service very good and workmanship excellent. I trust this company 100% and will be definitely be using them in the future. Paul, gentleman who fitted the door, done an amazing job. There is nothing there that person like myself (with slight touch of OCD) would have an issue with. Highly recommended local company that you can trust.

We used Three Counties to replace 7 windows at our property in February 2022. From the initial quotation, through survey to installation I was extremely impressed with them. The installation was completed by Dan and Cam who I cannot praise highly enough. Their workmanship and attention to detail / finishing was exemplary. They were polite and worked hard / efficiently to complete the job in 1.5 days. They took great care to protect carpets and furnishings whilst working and spent time tidying up, leaving the property very clean. I would not hesitate in strongly recommending this company.

The quote was the price (no hidden extras).The quality of the doors we purchased and the fitting of them was top notch It is nice to find a company that keeps you informed as regards fitting etc at all times We had a problem through no fault of 3 counties and they sorted it efficiently and effectively.We were kept up to date at all times. I have no hesitation in recommending them to anybody thinking of any form of double glazing. This revue would not be complete without a big thankyou to Kate and the fitters.

We are so pleased with our new bi-fold doors supplied and fitted by Three Counties. The job was done professionally and in the time frame provided. Dan and Cam took the upmost care on installation to ensure everything was perfect and they were a pleasure to deal with. Credit to the administration team also who kept us fully informed of the process and schedule. I would highly recommend Three Counties for their workmanship and already have to our friends, who have employed them to do their conservatory
