At A1 Complete Builders, our Renovations & Restorations service is devoted to breathing new life into older, damaged or heritage structures—allowing you to preserve character while ensuring safety, comfort and longevity. Whether it’s repairing damp, mouldy walls, restoring lime ceilings, re-plastering interiors with traditional materials or revitalising period facades, we bring expertise and respect to every project.
We begin with a detailed assessment of your property—looking at structural integrity, moisture ingress, historic fabric and architectural detail—then plan sensitive repairs that align with conservation best practices. Using traditional skills and materials where appropriate—lime plaster, natural renders, repair mortars—we combine them with modern techniques to meet current building regulations, energy efficiency and durability.
Our experienced team covers all phases: repair works, refurbishment, decorative restoration, internal remodeling and full project management. With A1 Complete Builders, your property is not merely renovated—it is lovingly restored, protecting its heritage while making it warm, safe, beautiful and fit for modern living.

When approached by the Diocese member of Kenwyn church to undertake repairs we was delighted as we have a keen interest in Restoration work.
This fascinating 15th Century houses a peal of eight huge bells all in superb working order suspended 50 foot up the Tower.
Also an impressive tiny solid granite spiral stair reaching from the bottom to the top.
The church received a full restoration between 1820 - 1862, We have been instructed by Diocese to erect scaffolding 80ft up the clock face and suspend around one pinnacle in need of urgent repair.
The clock face has also been removed and fully restored and painted.
We undertake our work very sympathetically and our highly skilled craftsmen take great care in their work.
The pinnacle has been dismantled and rebuilt with steel dowels being resin anchored into pinnacle stones and relayed in a bed of St Astiers Lime mixed with C.L.S 30 and a Prompt.
All internal walls have been manually raked out and re-pointed with St Astiers 3.5 Lime Mixed with a C.L.S 30 grit sand.
All work under the supervision of Roger Shaw Architects.
