I arranged a catflap for my elderly mother in her French doors and I have to say we were so impressed from start to finish. It looks fantastic!
Clear communication, nice and simple to deal with, they arrived when they said they would, and honestly did a first class job!
Their pricing is also very competitive. I would absolutely recommend this company to anyone who is looking for this kind of service.
Great job for first time cat mum
We’ve never had a cat and all of a sudden have a senior fur baby, from the moment I contacted BlueStar, the communication was clear and made everything very straightforward. The fitting was arranged within 8 days and a time slot given. Nathan and his partner let me know 45mins before they’d arrive and pulled in where I’d suggested right on time. When I told him we’d never had a cat before, he set the flap up for us to work with the microchip, demonstrated how it worked and the different settings. The fitting was quick, no fuss and they swept up after. Nathan even took a look at the door for us and recommended something for our windows. Payment was easy through BACS with the given bank details and exactly what I expected for a cat flap as I researched it. Great experience from start to finish, would definitely recommend and use this firm again.
Poor communication between office and…
Poor communication between office and engineer. Delayed fitting due to several reasons. Arrived late for fitting and demanded money to be paid whilst they were there, no invoice given, only a scrap paper of bank details. Once payment provided, communication cut off.

Cat Flap
We had a cat flap fitted by Blue Star. Excellent service - measured and fitted within 10days - they even went the extra mile to straighten the pane of in glass our other patio door. Good communication, friendly service and good value. Thank you!
Dog flap
A couple of years ago we had a dog flap fitted in our patio door by Nathan. It has been just what we’ve needed for our two labradors!
For some reason or another, the window had slipped and the beading has got trapped with the window. Nathan and Luke came out to fix it and has made it as good as new again for us!
Whenever I’ve needed anything throughout, they have responded very quickly and acted quickly too. I can’t recommend Blue Star Developments and Nathan enough!!
Needed a dog flap fitting urgently
Needed a dog flap fitting urgently, they were able fit us in within a couple of days of contacting them. We were unable to find anyone in the north wales area, very thankful they travelled for this job. Once the dog flap was fitted we needed a minor adjustment, after informing them they were back with us within a day. Sophie in the office was brilliant, always quick to reply and answer any queries we had. Great service from the whole team, would highly recommend!
Impressed
We were very impressed with the speed and service we received from the initial enquiry to finishing fitting the cat flap. Friendly, tidy and accomodating
Would highly recommend.
Velux window servicing
Had my velux window serviced and resealed due to a leak. Quick, clean job - window is as good as new.
I'd been quoted by another roofer who insisted replacing the whole thing was the way to go but was assured this was not needed. Nathan is very knowledgeable on best practices for Velux windows and offered some great advice on maintenance and what to consider if upgrading to motorised or replacing.
Trustworthy
The cat flap was installed in under 20 minutes, and I'm extremely pleased with the speedy and efficient service.
Great customer service
Great customer service, very friendly ☺️. Easy to book and very quick to fit. My cat loves it already so thank you!
30 year old Velux restored to new condition by Nathan and his team from Blue Star
Velux glass and seals repaired at a very competitive price.
Nathan and his Blue Star colleague were professional and helpful. They solved a long standing problem of a Velux losing excessive heat and looking unsightly.
I am well pleased and plan to use them for other window problems at the house.

Velux Window Replaced
Velux Window Replaced - Contacted them via email and within the same day they had someone on site sorting my Velux Window! WOW RAPID!! 5***** Thank you.
Untrustworthy
Nathan will turn up & tell you everything that's wrong with your roof & windows but he is the person who can fix it all, you will then be ripped off. The repairs carried out on my windows were condemned by Velux technical department & Blue Star gave a partial refund. If this review is disputed, Velux have the evidence. One word of caution, Velux will only rectify defective work carried out by an approved installer if its a new installation, you will not be covered for repairs
Update to correct Blue Star Developments inaccurate response
After completion of the so called 'full service' ? & payment had been made I took a more detailed inspection of the works & found that clear mastic had been used around the windows & one of the metal flashings had been forced up to apply 'blobs' of mastic to the screw heads so I contacted Nathan with my concerns' he stated that 'all the flashings had been removed & new seals applied'.
I left it a couple of weeks & contacted Nathan again & asked him straight - 'have you installed new seals around all the windows' to which he confirmed 'yes'. I also told him that all the missing screws he said he had replaced were not missing as I had found them on the roof & in the gutter when he had obviously dropped them
He said look, the works are guaranteed for one year so if there is a problem I will come back & fix it, so when the windows started leaking I got him back
I pointed to where the the water was coming in, to which he responded 'impossible' so I slowly poured a 1 litre jug of water onto the glass which ran down onto the bottom seal & in came the water, not just a drop but a continuous trickle, so there we have it - not all the seals had been replaced despite being told twice that they had.
At this point he blustered that he need to order some parts, his office would contact me to arrange for him to return & then he could not get out of the house quick enough
This was Oct '22 & I have never had any contact from Nathan or his office since so this is why I contacted Velux direct
Couple of other points
He mentions using bigger screws because the wood is rotten, there is no rot, he just has the torque set too high on his drill so its stripping the thread
With regard to his 27 years experience, well I also have some experience. I'm a City & Guild qualified joiner, I have a OND & HNC in construction & I'm a member of the Chartered Institute of Build with 40 years experience in the construction industry

Outstanding
Great, friendly and efficient.
Restored my faith in tradesmen. Terrific job so thankful for their services, nothing is too much trouble.
Amazing service from start to finish
Amazing service from start to finish. From my initial enquiry online to all the communication received its been brilliant service. Had a cat flap fitted in double glazed patio window, and also some velux windows cleaned and fixed which we've been struggling to get fixed for nearly 2 years now! Very friendly, honest and reliable.
Blue Star serviced 4 x Velux windows…
Blue Star serviced 4 x Velux windows for me recently. They replaced the seal and also repaired 2 frames that were showing signed of rotting.
I found Nathan and his colleagues to be efficient, prompt & friendly,
I would highly recommend Blue Star to anyone needing advice/repair of their windows
A more accurate review
I’m struggling to understand why some of the reviews of Nathan and his team are so outlandish. Nathan came across as the most knowledgeable of the Velux approved fitters. His team were punctual, respectful and efficient. A minor issue was corrected swiftly and without fuss.
