Bricklaying- 23 Mar 2026
Ian undertook some lintel repair work for us on our rented garages. We were happy with the first few repairs, but the last two were rushed and the work was left incomplete. Because the walls and lintels were not strapped correctly, the lintels have slipped, leaving the structure unsafe and unsupported. I have tried to resolve this amicably over the past few months, but he continually found reasons to delay fixing his mistakes. He is now completely ignoring calls and messages. We had more work lined up for him, but we will now be using someone else as we can no longer trust him to complete a job to a satisfactory or safe standard.

I'm a time served tradesman who's been in the building game since 1994. I became self employed 15years ago. Working solely in the north east. During the recession I had a spell at Sunderland college as a construction lecturer. I oversee all the jobs. From survey to last man. I have a proven track record of quality and care for the job. I cover all works and use only my qualified gas and electrical trades men. everything is managed through myself for your 1 point of contact. Thank you Davie

Extensions- 28 Oct 2020
Dave Market (DMP Building Solutions) came originally to view a lounge extension I was intending on building but we agreed on a kitchen extension due to front elevation restrictions imposed by the council. He talked us through the process and gave us a very positive vibe. He put us in contact with a surveyor and we went through a lengthy planning process which stalled our build for approx 9 months. No fault of Dave. The build started in July and completed in October. Council Building Inspectors threw a few curve balls in and Dave also had a few personnel changes to his team during the build, however his dedication and professionalism never wavered from the goal. We now have a beautiful extension with a sloping roof incorporating a velux window. A nicely tiled floor and panelled ceiling along with new additional units, tiling, plumbing, woodwork, plastering all done to a very high standard. Where Dave finds issues or wants professional assistance he has a wide range of experts at hand including, roofers, electricians, gas specialist, window/door fitter, kitchen fitters. He doesn't make do with tasks he uses these professionals to ensure things are done right. The outside has been finished in matching brick and slate with white pvc pipework and guttering. All very easy on the eye. I'd recommend DMP solutions to anybody wishing to have an extension built and I'm sure other work would also be completed to just as high a standard.

Nigel went out of his way to help me before Xmas, as my daughters room has been unusable since the storm a few weeks back. He fitted the work in to a time convenient for me, and all 3 lads were very helpful and friendly throughout, and also beat my other quotes. Thankyou Nigel and team, I will definitely recommend to others.

Stonemasonry- 2 Dec 2020
Fire damaged stonework above an electricity meter box and around a kitchen window. An awkward job but DSR were able to rise to the challenge. They turned up when they said they would so the job could interface with the window installers. They were also confident and competent enough to work in the vicinity of the meter box without the need to require disconnection which maintained our electricity supply. The quality of the finished stonework was very good and the lads were pleasant on site. All round good job and very satisfied, would easily recommend.

Cramlington Builders demolished our existing conservatory and built us a beautiful sun room on the same base. I was delighted with Michael and his team, they were really professional and very switched on. Michael was a great communicator and was ever so reliable. When the glazing turned up to site it was Michael who immediately spotted that the wrong glass had been delivered and that it was not safety glass. We would never have know that and Michael had the glazer return to site to swap the glass. We found the team to be happy in their work and they delivered a really great project for us on-time. The price was the cheapest of the three quotes received and we will definitely use Cramlington Builders again.
