Many of our projects are secured through direct appointment via word of mouth and repeat clients, reflecting the level of trust, accountability and continuity our clients expect. ​ Our approach is best suited to clients who value quality, organised delivery and the confidence of knowing their project is in safe hands. Our pricing is fair and competitive for the level of workmanship, management and service we provide, with a focus on delivering long‑term value rather than headline cost. ​ As well as taking responsibility for managing the build, we work collaboratively with our clients to ensure key decisions are clear, expectations are aligned and the finished result reflects what matters most to them. ​ While some projects are larger in scope, we also work on smaller, well‑considered projects for clients who value professionalism, sensible pricing and a hassle‑free delivery. Projects are clearly defined, properly planned and delivered in full, with many clients choosing to continue working with us on subsequent projects once trust and understanding are established.

Very pleased with newly installed sliding patio doors. The 2 gentlemen who installed it, were polite,friendly and helpful. They left the area clean and tidy. There was a slight problem with the lock, and they duly reported it to Louis Harbison. He came today to replace it but the barrel of the lock seems ok now. He is keeping the replacement barrel in case I have any more trouble. I would recommend this company for any work to be done

I couldn't be happier with the service provided by the Kierda Construction. We renovated our porch, toilet and bathroom (completely gutted). Quote was clear. They have completed everything in a timely manner. During the works I wasn't at home, but they kept me updated on everything. Very respectful of the property and high quality work done. Incredible attention to details from the whole team. Absolutely over the moon, I hope to spread the word for them because they truly deserve it!
