Customer Reviews
Look no further…
Nash was phenomenal right from the beginning. He was courteous, polite, and extremely knowledgeable. I regularly interact with various contractors, but Nash, and his team, are on another level. First and foremost, they are the very definition of quality. This means that they respect you, listen to you, and take care of you from start to finish. We had a property completely refurbished, and it was absolutely flawless. Forget every other company – all you need is Alexander Decor. Nash and his team are now my go-to for absolutely everything. Thank you Nash – God bless.

Highly impressed with the quality
I have used Alexander decor Ltd on 2 occasions, each time I was highly impressed with the quality of the workmanship and the attention to detail. First time I used them for painting and decorating and the second time was for full refurbishment the work includes bathrooms and kitchen fittings and tiles. All work completed well on time and within budget. I would recommend them to anyone.

I would definitely recommend
Nash and his team did a very professional job to fix the damage that was caused by a water leak in the flat above. The work was carried out to a high standard and completed promptly. It was a claim through insurance and there was a delay on the insurers side and Nash was very accommodating of the situation and overall I would definitely recommend.

Really cared about doing a good job
Nash and his team were great. Really reliable and really cared about doing a good job. We’re very happy with the results. Our ceiling had lots of cracks and they managed to make it look seamless again – beyond our expectations. The paintwork is really neat too. Nash was great in communicating with me all the time and tried to fit us into his workload as soon as possible. Highly recommend.

Courteous and very professional
The service provided was both courteous and very professional. Our requirements were carefully noted and we were given the opportunity to change our choice of colours three days before work commenced. Protective sheets were placed between the entrance door and the bedroom. The bedroom furniture was both removed and replaced. Masking tape was used liberally to protect surfaces and objects that were not to be painted. Both the speed with which the work was completed and the quality of the work surprised and delighted us. We would happily use this firm again and recommend them to others.

Such a top notch job
After a recent bad experience with another painter, It was an absolute relief to get Nashet and his team in and get such a top notch job. The quality of Interior plastering, coving moulding , painting was fantastic and I would wholeheartedly recommend, if you’re looking to get your home redecorating.

I’m so grateful to my Neighbour for recommending Alexander Decor. We had a big job so I really struggled to find the right team. Nashet and his team repainted ore 3 bedroom house, top to bottom, did a marvellous finish doing the spray painting. They also did a full refurbishment of my bathroom. All looks absolutely great. Can’t thank You enough. Already speaking to Nashet about squeezing us in for my son’s bathroom, too. Top job Guys. We well definitely use your services again, Keep it up

Really came up trumps for me
Nashet and co really came up trumps for me as I was left in a horrible position by tenants in my flat after speaking to him briefly he assured me the job would be completed to the highest level and on time and came out did a quote and within 5 days had the flat back up to scratch to the highest level. Finished the job a day early and was so easy to communicate with. Can not recommend him and his company enough.
