Fantastic service from start to finish. The team was quick, efficient, and friendly, and they made the whole process very easy. The work was done to a high standard and without any hassle. Highly recommended!Trustindex verifies that the original source of the review is Google.
Found Next Doors Ltd through Google & they had excellent reviews so gave them a try, & they were excellent from start to finish. After sending them a few photo`s & short video of the door problem, Alice in the office gave me a quote with a minimum & maximum price including labour & travel, so we knew exactly how much the cost would be if the door needed any replacement parts. After a deposit was transferred, Next Doors Ltd emailed with a slot at 24 hours later for the works, & the engineer texted me in the morning with an ETA on site. The door had the necessary work done & the whole job was completed in 90 minutes. This is the second time we have used Next Doors Ltd, & now we have a properly functioning front door to our restaurant. We would definitely use Next Doors again, & also recommend them to anyone else, absolutely first class. Fino Restaurant Bognor Regis PO22 6AA.
