Velux Windows Installation
David and his team provided an excellent and worry-free service. We had 3 Velux windows installed in a day with the team working tirelessly, efficiently and respectfully. The cost of the job was very reasonable and we will definitely be using Blue Star Developments for our future house projects. Highly recommended!

Flawless installation of Velux windows
Flawless installation of Velux windows.
Blue star developments have restored my faith in builders, I have had 2 Velux windows fitted in my new attic room and 2 windows serviced, they installed the windows within 2 weeks of our initial phone call, the work is excellent, there attention to detail is second to know and all members of staff I dealt with are knowledgeable and I will be definitely using again. I’d give 10 stars if I could.
Pet flap: Friendly, quick fitting and great price
I rang for a cat flap quote and had an instant very competitively priced quote and measurement done within a few days. Just over a week later my new patio door glass and microchip cat flap were installed very quickly and with no mess left. Nathan was very friendly, informative and went out of his way to help me with the setup. Highly recommend!
Highly recommended
I contacted these guys needing a Velux window and I cannot fault them. There was nothing they couldn’t do from the get go and they turned up when they said they would and were very friendly and accommodating. The price was all good and finished product excellent, it looks great! I cannot recommend them enough, Nathan is a top bloke and he does what he says he is going to do when he says he will do it 👍
Got a new cat flap this morning
Got a new cat flap this morning. Nathan did an amazing job! Job done within the hour - through my door which is covered in metal. Really please with how tidy the job is. He even brushed up after himself and helped me set up the app on my phone to control the flap. Thanks!!
Roof window expert
I was not sure about call out charge but after read the review I decided gave it a try. And I am so glad I did! They have fixed my window as promised. Really friendly and help. They have saved me thousand pounds to replace my roof window. I would highly recommend them.
Catflap installation
Had my catflap installed today. Incredibly pleased with how it looks, Nathan and his team were very friendly, and the price was very reasonable. Very happy with everything.
Cat flap fitted
David fitted a cat flap for us in a PVC door. It was arranged within a week, completed neatly and efficiently and very competitive price compared to another quote we received.

Reply from Blue Star Developments
Thank you to Blue Star Developments
Thank you to:Nathan, Gavin, Ethan and David from a velux windows first timer! Nathan patiently explained the process to me and answered my questions and was helpful and very friendly. Gavin is a Super Hero and good guy with a readable exterior! Fearless and trustworthy and Ethan is a star in the making and should go far if the modelling industry doesn't snap him up for his stature and amazing mop of hair! And David for fixing my loft ladders and straight talking.... Really friendly, reliable, hard working team who worked non stop in extremely hot and humid conditions, courteous and helpful, cleaned up after themselves and put in 2 velux windows in my loft record time! They've restored my faith and trust in tradespeople after a previous couple of bad experiences! Thanks Nathan for dropping by to fix the cable and giving me sound advice😊
New velux windows
nathan and his team recently fitted me a brand new velux window and repaired an older model for me, i was advised by numerous other companies that my 20 year+ old velux could not be repaired, nathan managed to strip my window down, install new glass and fully service it so it no longer leaks, looks like new, at a fraction of the cost of a new window, i’m so made up with the service that these guys offered, how professional they were and there customer service is fantastic. highly recommend, would definitely use thee guys again
I contacted Nathan about fitting a cat…
I contacted Nathan about fitting a cat flap in our double glazed unit..he came to measure up and give me a price the next day. Within a week the cat flap was installed on the date agreed. Nathan and his colleague were excellent, the job was done quickly, with minimum fuss and mess. He even managed to sort out another unrelated problem while he was here! Not often you get workmen who take pride in what they do and give the customer a high quality service. Would use them again without any hesitation.
Fabulous service to fix our blown velux…

V. neat catflap installation
David at Blue Star installed a microship catflap in our composite regency style door. He did a great job: dealt with the shape and material of the door really well to leave a neat and professional finish. Very reasonably priced too - thanks very much!
Excellent service
Excellent service, accommodated my dog flap at short notice. Quality job and lovely guy. Really went out of his way to make timing work and have a quality looking unit and fitted in no time. Highly recommend 😃

No show
Petflaps offered to install a catflap at my partners house. They cancelled the first appointment and didn’t inform my partner who had to chase them on the day. They explained they would be back in touch to arrange a further appointment and never were.
Unreliable and unprofessional, would certainly not recommend.
Efficient service
We had a Catflap fitted by these guys, very efficient, very professional, would highly recommend.
