GAP Avis 239

I purchased an expensive Rockdoor expecting a long‑lasting, premium product. Instead, the original door failed after just seven years with bulges and cracks. When I contacted Rockdoor customer service, I was told to speak to the installation company to make a warranty claim. After some nerve‑racking research, I managed to track down the original installer (who had since changed names) and provided images of the failure.

To their credit, the installation company were helpful and submitted the claim. Unfortunately, this was the start of a long and extremely disappointing journey. Since 2022, I have now had five Rockdoors, all of which have failed within a year of installation. The most recent door lasted only five months before developing severe bulges and distortion on the fascia.

I reported this latest failure in May 2025, and the installer passed the information to GAP (Rockdoor). I then heard nothing for five months. When I chased for an update, I was told that GAP refused to replace the door under the 10‑year warranty because the original warranty period had expired — despite the fact that this particular door had failed within a year of being fitted. I was assured the issue would be escalated, but after another four months and another chase, I received the same response.

This product clearly suffers from serious manufacturing defects. Although marketed and priced as a premium door, the quality has been consistently substandard — especially when compared with alternatives costing half as much. The only option I have been offered is to take the installation company to small claims court to recover the cost of replacing the door myself.

Based on my experience, I cannot recommend Rockdoor products or their customer support.

Easy to order online. Excellent choice of delivery slots. Good delivery updates. Really pleased as usual with the whole purchasing process

The products are amazing quality. I had been undecided about changing my windows and doors as hadnt seen anything that appeared much better than what I had. Then along came GAP windows and doors.. wow.. they are such quality. Look so good. I went for the pebble colour on recommendation from sales team.. its fabulous. I am so happy.

Great experience dealing with Mark Dickel from Slough , very helpful, very responsive and great knowledge. Makes it very easy to deal with gap !!!

I ordered materials a week and half before i needed them on site. I wanted them delivered the day before so my team could start work the following day. When they arrived nothing on site and I had to stand the team down. Trying to reach the branch was impossible and had to waste time with Customer Service. If it was clearer that delivery's dates are estimated I would of allowed more time, very disappointed.

I can not recommend GAP highly enough. Caroline always goes above and beyond to get our orders sorted and delivered extremely quickly. Always a 5* Service.

My recent order arrived in good condition and and all there except I ordered mahogany beading and got light oak which the delivery driver insisted it was mahogany could not send it back as I was fitting it the next day

I ordered white upvc cladding for a ceiling and communication and fast delivery with a friendly helpful driver made the whole process EXCELLENT.
Provided a catalogue and card too and ordered more things the very next day when I realised it was a local company.
Great competitive prices, and easy to use website and communication.
On my speed dial from now on.
Great service and products high spec.
Thank you very much

I have a Rockdoor which has developed a fault. It has a 10 year guarantee. From when I first made my claim it has taken Rockdoor a year to replace my door. I would have given 4 stars but I feel there should have been better communication throughout my claim.
I am happy with my new door.
Would not advise a dark coloured door with a south facing aspect as I believe this contributed to the issue, if only I knew of this in advance. Rockdoor says that they have made improvements to their doors, only time will tell.

I used the chesterfield branch and I cannot think about enough. Good things to say about how friendly and helpful the staff were and how the customer service was. Absolutely beyond reproach and amazing......

Visited wombwell store today and delt with Danny Goddard who his customer service was excellent would definatly recommend gap.Also I would like to mention Tom Branford who also had his input,
We wish all company's where has helpful nothing was to much trouble the company should be lucky to have people like this working for them. Thank you

I have just completed a small building project.......I bought all the facias, soffits and guttering from GAP in Helston

A big THANK YOU to Matt Smith, Chloe and the rest of the team in Helston for great service and support.....real people who care about their customers

Keep up the good work guys!!

I only come here for my guttering, soffit and fascia. Darrel, Steve and Turkish have been there for me since I started and they are the loveliest team! Nothing is ever too much bother, always anticipated my upcoming jobs so they would have stock in.

Nicola, Claire and Daz are all fantastic. Know exactly what you need and always help out. Fast and reliable service. That’s why I’ve been using these for the past 5 years and I’m more than happy to carry on

What an amazing experience from the ladies down at GAP Rotherham. Always tip top on price and stocked up to the rafters!

Would definitely recommend for your plastics goods.

The whole team have been very helpful from start to finish, also thanks to Pete for putting his self out with many deliveries

PLEASE BE AWARE! I purchased a Rockdoor from these people in 2018, a composite top quality "Elite" range door. It's now bowed to the point that it's started to crack....after 6.5 years. These doors were sold as top quality, they definitely are not. The door has bowed so much that it's now cracking in several places, Gap are not interested at all. Please bear this in mind if you're considering using this company and read other 1* reviews of which there are many - it's extremely disappointing, I now have to buy a new door, surely it's reasonable to expect a door to last more than 6 years? Whatever else they say and whatever excuse they give, 6 years should not be the life of a Rockdoor..."a top brand" apparently. I'm in business, if I treated my customers like this I'd soon be out of business! Just extremely disappointed in a company that I thought was decent, I was wrong.

Please read other reviews about their doors, I am far from the only one who has had this experience, it's outrageous. When I told them I'd take them to court, the response was "go ahead".

Easy to use when online ordering, but what made it better was I miss ordered somethings I call my local store and they was very helpful and made it all so easy to charge

I’ve been in the Building Plastics industry running stores for over 20 years. It takes a lot to impress me but I must say Gap Wolverhampton are switched on, customer focused and a credit to the company. Whether it’s Adam the branch manager or Rob the sales manager- they treat every order big or small with the customer in mind. It a pleasure to deal with them.

I required assistance with invoice reconciling earlier today, and requested some assistance from the customer services personnel.

I was so pleased that my call was answered almost straight away, and that the extremely professional and polite lady provided both answers and solutions to my issues raised.

Within minutes invoices were retrieved and detailed information confirmed - and with no fuss at all.

What a refreshing change!
A well deserved 5 stars!
