Installation of dividing doors

Absolutely delighted with the installation of pre-finished oak doors to divide our dining room and lounge. From initial contact through to quotation and then installation the service was exceptional. Friendly, professional and skilled staff. Very professional team, minimal painting of wall required after fitting and area left really clean and tidy. We would not hesitate to use this company again and will be recommending to friends and family.

Excellent speedy replacement of chimney.

Due to stormy weather, a chimney was close to collapsing. It was so bad that the chimney was swaying in the wind! To prevent the chimney from falling down on the roof KJN Home Improvements Ltd fitted scaffolding within 24 hours. KJN then removed the old chimney & built a replacement which has been much admired by the neighbours. KJN were most helpful in a very dangerous situation. They were also very easy to deal with - always available to discuss the progress on the job.

Totally unreliable
I chose KJN Home Improvements as they are the closest Which? trusted trader. When I first phoned this builder for an estimate, I was offered a time about 2 weeks later. I accepted this appointment and booked UNPAID time off work to be in when they came. I stayed in anticipating their arrival and waited and waited and waited. Two hours after the appointment time, I phoned their mobile to check they were still coming. The only explanation given was that Russell was meant to come. There was no apology for not turning up. The man explained he was concreting and clearly wanted to end the call immediately. He assured me I would be phoned back after about an hour when he got back to the yard. I stayed in and waited and waited and waited. They didn’t bother to ring me back at all. I am very annoyed at this apparently unreliable, unrepentant and untrustworthy builder. I stayed inside on this first warm sunny day of spring waiting and waiting and waiting for this builder. I couldn’t go out in the garden to enjoin the sunshine. I couldn’t go out in the garden to help the wife paint the shed. I couldn’t take the dog for a walk or even go in the garden and play ball with her. I wasted most of a day waiting on this builder and had to take unpaid time off work to do so. I do not recommend this apparently unreliable builder with very poor customer service whatsoever.

The trader replied (on 20/04/2021)
Please accept our apologies.We agree on this occasion that you did not receive our usual high quality service.On your appointment date the company received 4 positive Covid-19 results from staff which caused unprecedented demand.This put increased pressure on an existing large scale project and for this we can only apologise. Our reviews show that this is not our usual conduct. We are sorry that you took unpaid leave and stayed in all day. Please accept our sincere apologies in this matter. Kind regards KJN Home Improvements LTD

I have had 3 buildings works completed by this builder and I have to say all jobs were completed with professionalism on time and with very exacting standards. Communication was excellent and any issues i had were quickly resolved. All on all i have no trouble recommending this builder with complete confidence.

Roof, Windows, and Door replaced

KJN have rebuilt the roof above a ground floor bay window and front door, which had been leaking in bad weather. They also replaced the bay windows, front door and side window. To repair the roof a new oak gallows bracket was made and fitted at one end, and a support post was added to support the middle of the roof. The roof was fully re-tiled, and the cavity trays above the roof were replaced. New lead work was also fitted. The work has been completed to a very high standard, and we have been impressed throughout with the way in which the causes of the problem were identified and resolved - always with our full involvement. Two recent storms have tested the work out and it has passed with flying colours! We will be happy to use KJN for future work on our home.

I have had a patio laid by KJN and I would recommend their excellent work. The men doing the work were on time hardworking and considerate of the current social distancing rules. The work is really lovely and I couldn't be happier with it.

I have used KJN over quite a few years to replace windows, French doors and external doors. The quality of the goods supplied is always A1. The quotes are accurate, communication is easy fast and friendly. The fitters arrive on time and on leaving ensure that everything is looking clean bright and perfect. I wouldn't dream of using someone else!

From the start KJN Home Improvements have been great. Dave Stamp was there from the beginning to advise us on things and Georgia was extremely efficient and supportive. Mick was brilliant doing all the hard graft of knocking walls down/building walls up and Andy and Mark were fantastic in installing our kitchen and flooring. We are so pleased with the finished results. We would thoroughly recommend KJN and hope to use them again in the future.

An excellent company to deal with from start to finish. The quality of the windows and door are just so much better than the original ones and better than many of my friends who have had windows and doors fitted by other companies. The two fitters Chris and Rich are an asset to this company - polite, tidy and went the extra mile to ensure that the work was first class and exceeded all my expectations. Thank you to you all
