Your Local Builder

We’ve been operating in Lytham for many years now, and we take pride in the fact that we’re a friendly, local business. Based in Marton Moss, we’re about three and a half miles away from you, which has a number of advantages. For example, should we need to return to Marton at any time to pick anything up, it won’t break up our work too much. We’re also perfectly placed to drop by should you have any questions for us, and we’d be more than happy to talk everything through with you.

The Importance of Transparency

Many of us have been exposed to horror stories about fraudulent builders who become notorious for their poorly executed or incomplete work; these rogue tradesmen are always difficult to reach and then take off to be never seen or heard from again. Here at Keystone Construction Limited, we always lead by example and ensure the honesty and reliability of every builder we employ. Customer satisfaction is our number one priority, which is why we guarantee to always maintain clear and frequent communication with our clients regarding all of the construction work being done on their property.

Our professional team of builders has accumulated over 20 years’ experience of working on loft conversions, house extensions and structural improvements. We are committed to overseeing all of our projects at every stage, including the physical construction work, the planning and designing aspect of your renovation, and any post-construction consultation you might require.

Many of our Lytham customers are understandably concerned about how their renovation project will affect their daily lives; all of the noise, dirt and disruption involved with construction work can be worrying, especially if you have pets or young children in the house. Every builder working for us is extremely considerate of these concerns, always ensuring they consistently arrive on time each day to keep the project moving ahead as scheduled, as well as maintaining a clean and tidy construction area.

Local Testimonial

Excellent, quality builder. Worked well with my architect, buildings inspector and
neighbours. Produced a first class development of my property. Always willing to listen and negotiate changes to plans as required. Keeps the site as tidy as possible each day when finished. Thoroughly recommended.


Keystone Construction, David, came to our rescue after we were let down by another builder. He was quick to give us his quote and managed to squeeze us in his busy work load. Both he and his workmen are reliable, punctual and hard working, even refusing “brews” because they wanted to get on. The standard of work is very good and the workers cleaned up after themselves on a daily basis.


Simon Cook

I got intouch with Dave based on his reviews and practically begged him to do some work on my house due to his availability. He did a substantial amount of structural work and I couldn’t be happier with the work, his speed of work, cleanliness and most importantly his advice and guidance throughout the whole process. He pricing was incredibly reasonable. On top of this you couldn’t find a more down to earth and likeable fellow.


Builder you can trust, It’s been a pleasure to meet David. He is a builder who will give you honest advice. Regardless if he gets the job or not
A man you can trust. Our condensation issues are now resolved thanks to David.

Carole Hewitt

David and the team carried out the removal of a chimney breast, supporting the stack and finish to a very high standard. Throughout the whole process David was professional and was always available (day and night) to answer any queries regarding the job. He was always on time and finished the job well within timescale. I would highly recommend Keystone Construction and will definitely be using them again in the future *****

Ben Hopes

David & his team were excellent, prompt daily timekeeping, very professional, excellent workmanship, very clean & very reasonably priced. I think that throughout the works David & his team maintained the very highest standards.

Ron Trewartha

David and his team were the only one of several firms to correctly identify a problem (existing conservatory built over the cavity wall trays leading to water flooding in over the internal doors) and who were willing to address it due to a sloping apex roof, The roof was replaced with a flat roof, cavity trays installed so that water ran onto the roof and therefore to the gutters, interior ceiling fitted, ceiling and water-damaged plasterwork replaced. Superb job and at a reasonable price. Would recommend without hesitation.

John Burke

Absolutely excellent service from start to finish. Extension and internal refurbishment delivered on time, on budget and with exceptional quality workmanship. Would very highly recommend David and his team. An absolute pleasure having the team here and would definitely use them again. We were told the timescale from agreeing the work to its start date and it has been well worth working to that schedule for such high quality

Rita Trewartha

David couldn’t of been more helpful in all aspects of our extension..
Great team of guys and really happy with the finish ..

Andrew Beard

We used David for the building work needed to have bifold doors fitted. From our first meeting, David was professional, friendly and gave us a lot of confidence. He kept us fully informed both before the work and during, and his team were professional and kept a very tidy work area, ensuring minimal disruption to our day to day activities. To look at the brickwork you would not know that any work had been done as he went out of his way to ensure we had as near-identical brick match. We would not hesitate to recommend David and Keystone Construction and will be using him again for future building work.

Nat Beck

Keystone construction completed a side and rear extension on our bungalow including extending the kitchen and bathroom, demolishing old garage and erecting side extension of boot room, utility room and garden room. The completed project is of a very high standard and even my neighbours have commented on the excellent brickwork. The team were very experienced and ensured all elements of the build were considered, meeting all building regs and they went over and above what was expected to ensure neighbours were not overly impacted. From beginning to end I was kept informed at all the various stages and what would happen each week and received great advice. The build was delivered on time and I would not hesitate to recommend Keystone Construction for any building works required in the future. Thank you David and team great job!

Jane Higgs

We are so happy with our newly extended and re-designed open plan kitchen/diner/living space.

David and his team have given us the perfect environment to enjoy family life to the full, we can now cook, play with the kids, and watch our favourite programs together, I don’t think we have been in the living room since!

David offered us his advice and guidance throughout the whole project as well as managing all the aspects of the build, from digging out at the start to polishing the cupboards to our new kitchen right at the end.

We were apprehensive at first about remanding in the house while all the work as being done, especially with two young kids, but David ensured us at the end of each day that everything was left spotless and clean as possible, really minimising the impact on our day to day living.

Even when the odd glitch came up, which will happen on any build, he found a solution straight away and with urgency.

I would hesitate recommending David and his team to friends and family.

Darren Tomlinson

We moved to Lytham a year ago having bought a large three story Victorian semi. We wanted to upgrade the house (Full refurbishment) and the garden/garage and chose David Watmough of Keystone Construction.

We’re delighted we did!

The quality of all his work is superb.

He and his team were completely reliable, turning up to site every morning on time.

They were professional from star t to finish.

We can certainly highly recommend Keystone Construction.

Keystone proved entirely reliable and sympathetic towards our instruction and design schedules. The personnel were punctual and worked tirelessly, sometimes in difficult conditions

May I thank you and your team for the efficient way that you dealt with my damage rood, cause by the recent gales. I would have no problems in recommending you to others.
