My first experience with the company…

My first experience with the company was whilst driving through Thetford in a 30mph speed limit near a school at a busy time of day where the van
DL70 KKJ came hammering up behind me and, i do mean hammering. The driver sat on the white line separating the 2 lanes of the single lane carriageway in an attempt to intimidate me. I cannot tell you how close he was to the rear of my car. If I had been silly enough to brake check him, he'd have hit me. In light of this i slowed for the incoming roundabout very gently to avoid this from happening. When we finally got to the A11 north bound, I accelerated away from him sitting in the outside lane in a solid line of traffic. It was a busy friday afternoon. He soon caught me up in lane 1, undertook the car behind me, cut him up and pulled out into lane 2 behind me, again inches from my rear. I decided the best solution was to pull over and let him go. As they drew along side me, the passenger, with the window down, decided to clench his fist at me and call me a c%$t. The driver then swerved infront of me. I usually have a camera running, today I didn't have it in the car. It would have been given to Norfolk Police. Never again will I leave home without it. They then roared away, pulled back out into lane 2 after undertaking another car and basically for them, it was a case of eat sleep rave repeat. Clearly the norm for these 2 to behave and drive like that, way in excess of the 60mph speed limit for a large sprinter type and size van. They showed a complete lack of respect to other road users and the law. Comfortably 90mph or so. All this while driving a company sign written vehicle. Definitely not professional, respectful, mature or intelligent for their age. I personally would not want this company or its staff working in my house. Would YOU. Definitely not good, decent and honest people i could trust. They are a disgrace to the company name and their actions constitute gross misconduct. The vans are most likely tracked and the director must be aware of how his vehicle is being driven. It is his responsibility to monitor his staffs driving and take action should it be necessary. Absolutely shameful, unprofessional conduct.

A Very Good Company

The two installers, Jack and Nick, were very polite, helpful and prompt. They arrived on time throughout the job, which last three days. Their work was excellent, and they provided a lot of useful tips and advice. The company, Sash Window Preservation, have also been excellent. From making initial contact, through to completion, the company have always been helpful and courteous. I would recommend them to anyone contemplating work of this nature, and should the need arise, I would not hesitate to use them again. They are extremely good, and worth the money.

Fantastic window restoration- goodbye to condensation and outside noise

We’re absolutely delighted with the restoration of our Victorian house window. The service provided my Nick and his team was outstanding from start to finish. We used to have heavy condensation every morning and had to use our Karcher window vacuum daily, but since the restoration the condensation has completely disappeared. The noise reduction has also made a big difference. Best of all, the window has been beautifully restored while maintaining the original character of our property. Highly recommended! 😊

I’ve had a really positive experience…

I’ve had a really positive experience with Sash Window Preservation so far.
After researching several companies, I spoke to a few that were cheaper and some who were very quick to criticise other firms. A couple even offered ‘lifetime guarantees’ which I actually question if they exist and made big promises. But in my experience, over-promising doesn’t always lead to the best outcome
I’d much rather deal with a company that is honest, realistic and clearly knowledgeable who don’t talk bad about other companies, they have been a pleasure to deal with so far.
Ricky was incredibly informative and took the time to explain everything properly. You can tell he genuinely understands sash windows. There was no pressure, just clear advice and transparency.
The team answering the phones have also been fantastic, professional, friendly and very responsive. Thanks Davey.

I’m genuinely grateful that Trustpilot exists because being able to read honest, consistent reviews gave me the confidence to choose quality over just going with the cheapest quote with a company who don’t appear to have reviews. I’m a firm believer that you get what you pay for.
Sometimes paying a little more is worth it for peace of mind.
Really looking forward to getting the windows done.
Thank you SWP

Perfect new windows

Jack, Nick, Daryl and Shay did a marvellous job, draughtproofing and double glazing our 5 beautiful sturdy Victorian sash windows. They worked in the most horrible conditions - freezing cold, wet windy weather - stripping the frames and refitting them with the new glass and the insulating strips. They cleared away thoroughly afterwards, and were always friendly and efficient. Highly recommended.

An end to draughts

We have had work done to draught proof windows in our old house which has proved very worthwhile and recently had work done on our old front door which seems to have been successful. The workmen have been very nice to deal with arriving on time, working carefully and quietly, leaving remarkably little mess and left us with a warmer home. We look forward to the next phase of their improvements to our home.

Phenomenal service and extremely high quality

These guys are top drawer. I have dealt with a lot of people with my large and somewhat problematic listed house, and these are the best.

They are high quality windows, very impressive, and very individually done - which helps when your windows often have different sizes and can be wonky in places.....
