After sales/customer service awful

We first used Sehbac 15 years ago at our previous house. The whole experience was very good and the windows and doors of good quality. We had a salesman who came round David Townsley who explained all well.
We decided to use them again because of our previous experience. Before I go any further the fitter Tony was excellent. Twice the wrong windows turned up and their install dept blamed it on us, even though the design was there in front of them. We had patio doors fitted, within a month the handle wouldn’t lock. This took them 3 weeks to attend. Within 48 hours the same again. Different person turned up again another 3 weeks. Then one of the patio doors leaked ruining a new carpet they said 3 weeks and couldn’t come any sooner even though water was coming through the door onto the carpet. Now one of our windows do not close properly. I rang up and frankly the customer service was very rude saying they had sent me a email, which I still haven’t received and again 3 weeks. It is because of where I live and no services out this way. I live in a large town 20 miles from their depot so a 30 to 40 minute drive depending on traffic. Now thinking about a conservatory but will be looking somewhere else. A shame really, because they used to be so good and efficient.

Our Experience Replacing an Old Conservatory

We recently had our old conservatory replaced by SEH BAC, and we could not be more delighted with the results. The entire team did a brilliant job from start to finish. We cannot praise their staff and guidance enough—they truly are fantastic people to deal with.
Dave and Carl, who carried out the fitting, were both extremely friendly and thoroughly professional throughout the process. Their attention to detail and dedication to their work were evident every step of the way.
Cliff and Kevin oversaw the project and consistently went out of their way to assist us, ensuring everything ran smoothly and addressing any questions we had promptly.
We also want to mention Mark Harris, who was incredibly helpful and accommodating when we needed to delay the start of the project. His understanding and support made the process much less stressful.
Overall, we highly recommend SEH BAC to anyone considering home improvements. Our experience has been exemplary, and we are extremely grateful to the entire team for their professionalism, friendliness, and outstanding service.

Fabulous service from start to finish

Fabulous service from start to finish

I ordered two new doors and the service throughout has been exemplary.

Everyone who I dealt with has been a real credit to the Company - Mark at the Chelmsford showroom who helped with the order, Scott, the surveyor (who came out the following day!) and a very special mention to John and Paul, who installed our doors. They were a pleasure to have around, tidy, courteous, worked incredibly hard, on a very cold day, and did a wonderful job.

Our new doors look fantastic, were delivered ahead of expectations and we even had a visit from Gary at the end of the day to follow up. Very satisfied and I wouldn't hesitate to recommend them.

Amazing doors amazing employees. Couldn't have done anymore for us

Darren and Tyler who fitted the doors were absolutely amazing. Did an incredible job and were so friendly and answered all the questions we had. The doors look amazing and the fit is incredible. We could not be happier. Just to say again Tyler and Darren are an absolute credit to the company.

We have just had our sliding doors fitted in our dining room by Darren and Tyler, and I wanted to share how impressed we were with both of them. Not only were they respectful and polite throughout, but the quality of their workmanship was exceptional. They clearly took great pride in ensuring the final result was perfect, and the doors have been installed beautifully. Thank you!

We had 2 replacement doors and a window, fitted very quickly. Manager Gary showed up at the end of the job and explained the door locks to my wife.

Fantastic company to deal with

every contact with this company has been a pleasant experience and every member of their team has been on time.
Marc & Nigel, who did the installation this morning, were clean, professional and helpful, they didn't waste any time just got on with the job. There was no mess when the windows were fitted as they automatically cleaned up after themselves. Marked improvement on some workmen.
If you are looking for new windows or doors these are the people to use.

Good past experience, but billing and site care issues this time

I chose this company again because they previously carried out two conservatory projects for me to a good standard. Based on that experience, I expected a similar level of professionalism. Unfortunately, this installation did not live up to those expectations.

While the window installation itself was completed, I experienced serious issues regarding billing and site care. I was invoiced £1,560 (including VAT) for an itemised scaffold to the rear elevation. That scaffold was not supplied or installed. A different and more limited access arrangement was used instead. Despite raising this promptly and paying the undisputed balance, the company maintained that the majority of the scaffold charge was still payable.

In addition, the workmen left a significant amount of debris on the top-floor rainwater gutter/parapet, including wood chips, metal fragments and screws. I have photographs of this. The area had to be cleaned separately to avoid blockage and potential damage, and I was not compensated for the cost of arranging this clean-up.

I attempted to resolve these matters amicably over several weeks, but the issues could not be resolved. The dispute has now been referred to the small-claims process and is awaiting a decision.

Given my previous positive experiences, this outcome was particularly disappointing. Prospective customers should ensure that access and scaffolding charges are clearly defined in advance, that what is invoiced matches what is actually supplied, and that the site is thoroughly checked after works are completed.

We’re disappointed to read this review, particularly given our previous successful projects for you, but we feel it’s important to clarify the facts for transparency.

On the day of installation, the independent scaffolding company was unable to erect the originally planned scaffold with full platforms due to the design and layout of the property, which only became apparent on site. In order to proceed safely and remain fully compliant with current Health & Safety legislation, the scaffold company worked directly with our installers to amend the access design and provide alternative, compliant fall-prevention measures. This revised arrangement still involved specialist equipment, labour, and cost.
We provided full and open transparency throughout, including sharing the original scaffold quotation, the amended invoice received from the scaffolding company, and adjusting our own invoice accordingly. As is our standard practice, customers are only charged for actual costs incurred — we do not apply mark-ups to third-party scaffold charges, and we will always amend invoices where costs change.
Regarding site condition, we take cleanliness seriously and regret that you were dissatisfied. Had this been raised at completion, we would have addressed it promptly, as we do with any genuine snagging concerns.
We made multiple attempts over several weeks to resolve this matter amicably and fairly, but unfortunately agreement could not be reached. As noted, the matter is now with the small-claims process, and we will of course respect its outcome.
We stand by our commitment to being fair, reasonable, and transparent, and the many positive reviews from our customers reflect this approach.

I am a returning customer having previously installed a conservatory with Sehbac. Nigel who is the local sales agent is a pleasure to deal. This time I had my windows and a door replaced and the process was seamless. Nigel and Marc arrived on time, were very courteous and took care of the property while they did their work and made sure evrything was tidy. The work completed in two days ahead of schedule and they were great to deal witgh. So far, no issies with the product.

Shocking, felt harassed

Shocking, became intrusive and harrassing.
I filled in a form through fine line windows to find out my nearest retailer, no enquiry or asking for a call back. I then received at least 23 calls, numerous emails and messages over 2 days after repeatedly requesting them to stop. Driving me mad, intrusive and harrassing behaviour from them.

We visited the Colchester showroom

We visited the Colchester showroom, and were introduced to the sales director (Adrian) who talked us through some options. That very same day their sales rep Elliot Miller visited our property and measured up and gave great advice on our options. He was with us for as much time as we needed, and was very informative and engaging. We even chatted about his pokemon collection with my 11 year old.

It was a great customer service and we were very pleased to go ahead with our order - confirmed today!

Thank you Elliot and Adrian for the great customer experience.

Customer Services and After Sales Services

We have been a customer of company for very many years and on two occasions we have required their services on an urgent basis. This was of course recently supplied and issues fixed on a very quick basis.
It is important for major companies to ensure that after sales service is in place and this is without doubt the best that I have ever experienced.
After Sales Service and maintenance is only as good as the administrative personnel at HO and as my last problem was linked to security, the repair was dealt with great speed and efficiency. This was done by Siobhan and Jason and my thanks to them
