Case Study: Window Replacements & Porch Design for a Beautiful, Energy Efficient Home

When deciding to update your property’s appearance, it’s important to understand why your windows need replacing and what you want from an installation. Your old windows may be starting to look tired, for example, or perhaps they’re letting in noise or the cold.

This Worcester Park home in Surrey has been both modernised and insulated thanks to our stunning collection of uPVC windows and doors.

The Project

Our customer wanted to update the look of their home, yet find a reputable company who could offer quality products at fair prices.

Deciding to replace their old windows, the customer chose to start with the front of their house and porch area. They initiated the process by conducting an online search for window installers in their local area and requested quotes from several companies.

After speaking with Paul, Merton Window’s company director, they were happy with the quality of products we supply and our honest, competitive pricing. With front window replacements and a new porch design required, we wanted to offer a range of options to suit the customer’s tastes while providing more functionality to their home.

The Solution – Modern, Weather Resistant Windows & Doors

This home’s new look has been created using one of the most popular materials on the market – uPVC. uPVC windows and doors not only boast an attractive style but are incredibly low maintenance and energy efficient. We replaced the lounge bay window, two bedroom windows and fitted a new porch design, installing white uPVC casement windows and doors.

The installation resulted in a fresher, modern feel to the home’s appearance while reducing the noise pollution entering the property. Adding further insulation, they provided improved thermal efficiency before the colder Winter weather set in. A smooth installation from start to finish, we completed the project to the highest specification with our professional, courteous team tidying up afterwards.

A hassle-free, efficient installation for this Surrey home.

Customer Testimonial

Most importantly, what did our Worcester Park resident think of the installation?

“We choose Merton Windows because we received a fair quote for good quality products.  Paul was very friendly and helpful, but without any pressure to go ahead with a purchase.  The whole company were very approachable for any questions that we had.  The installation was clean and quick, again with very friendly guys.  Paul visited several times to ensure everything was going to plan.  I would definitely recommend Merton Windows”.

A huge thumbs up all round!
