Highlights

"What can I say! Liam, Keiron and Bernie were professional, understanding and helpful during our works: Replacing a 25 year old girder supporting our main bedroom. They explained the process at each stage. We felt confident with their knowledge and experience dealing with a complex situation and the works completed to a high standard. We will definitely use them again and recommend them."

"After buying a house with many problems i contacted TRI DYN & I'm so glad I did. Throughout the whole process there was good communication, good time keeping, always friendly, honest, tidy & polite. I had a leaking wet room that needed taking out & a new bathroom installed. I couldn't be happier. Liam & Sian work there socks off & are a great team! Always giving me the best advice along the way. I also found a leak on the chimney & condensation in the attic. Again I called TRI DYN & the knowledge, experience & workmanship was brilliant. I can't recommend these guy's highly enough!"

"What can I say other than I would beyond recommend Liam. From the moment he came to give me a quote and look at the job I had a good vibe from his friendly attitude to his expertise when I was asking questions. The work was carried out efficiently over 2 days as agreed. The areas were left clean after each day and most importantly the work was completed to a high standard. I can not recommend Liam enough. Such a nice guy with great silicone skills which is very important to me. Approaching Liam throughout the job was never an issue and my happiness with the work was his priority."

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
