Box Gutters
Box gutters carry high volumes of water and fail catastrophically if lined incorrectly. We construct heavy-duty Code 7 and Code 8 lead box gutters that handle London downpours and last for generations.
When You Need Box Gutters
Overflowing internal box gutters during moderate to heavy rainfall. Water penetration appearing on top-floor ceilings near parapet walls. Splitting, cracking, or thin spots visible in older lead box gutter linings. Undertaking a comprehensive roof refurbishment on a listed commercial or residential building.
How We Do It
We clear existing debris and inspect the timber gutter substrate for rot or structural sag. We lay specialist separating/underlayment fleece to protect the underside of the lead. We install heavy Code 7 or Code 8 lead bays with correct expansion steps and welded joints. We connect outlets, hoppers, and downpipes to ensure unrestricted water drainage.
What to Expect
Box gutter renewal timelines vary by length, but most standard residential runs are completed within 3 to 5 days.
