A failed gutter drops rainwater directly against the wall — the leading cause of penetrating damp on rendered and cavity-wall properties. The cost of leaving it ## What actually happens when this is put off. ### If it's ignored - A leaking gutter over a soakaway can wash out foundations over a season. - Water tracking down the wall soaks insulation and rots window heads — internal damage that costs multiples of the gutter itself. - A rotten bargeboard lets wind-driven rain into the roof void from the gable end. ### Common mistakes we clean up after - Silicone-and-hope repairs on gutter joints — buys a season, causes a mess in the next. - Fitting new gutter to a rotten fascia — the new gutter sags within a year. - Wrong fall to the outlet — gutter never fully drains and joints leak permanently. Our process ## A predictable path from first call to guaranteed sign-off. - 01 Free inspection Roofline check, gutter fall test, and joint / bracket assessment. - 02 Fixed written quote Named products, colour, and price — 3–4 day turnaround. - 03 Strip and prep Old gutter and bargeboards removed, fascia condition confirmed. - 04 Install with correct falls Brackets set to fall, gutter clipped, joints sealed properly, downpipes plumbed to outlet. - 05 Test and sign-off Water-tested where practical, site cleaned, workmanship guarantee issued. What you actually get ## The outcomes — not the sales talk. Correct falls, first time Gutter drains cleanly to the outlet — no permanent ponding, no chronic joint leaks. Colour-matched to roofline White, black, anthracite grey, brown — matched to fascia and downpipes. 10-year workmanship guarantee Written, from GNB Flat Roofing. Fixed price, no call-out fees Survey free, quote fixed in 3–4 days. PL & EL insured Full liability cover throughout. Neil quotes it and installs it One trusted point of contact. Specification detail ## The technical honest version. Guttering looks simple. Getting it to last twenty-plus years without a leak is not — it comes down to falls, bracket spacing, joint detailing and the state of the fascia behind it. ### Gutter profiles Half-round, deep-flow, square and Ogee profiles — sized to the roof area draining into them. Under-sized gutter overflows in heavy rain no matter how well it's fitted. ### Bracket spacing and falls Brackets set to fall gently toward the outlet, at manufacturer-specified centres to prevent sag between fixings. ### Joint detailing Correctly seated seals in gutter unions — not sealant applied on top after the fact. ### Downpipes and outlets Sized to the flow, plumbed to gulley or soakaway, with swan-neck offsets where the wall geometry requires it. ### Bargeboards The angled boards at the gable end. UPVC replaces perpetually failing painted timber, installed with correct laps and cover trims. ### Fascia condition check New gutter on a rotten fascia will sag. We check the fascia before fitting — and quote fascia replacement upfront if needed rather than after. Frequently asked ## Questions we answer at almost every survey. How long does a gutter replacement take?+A typical semi is a day; a detached with bargeboards, 1–2 days depending on access. Can you do just the gutter, or do fascias always need replacing?+If the fascia is sound, gutter-only is fine. We'll tell you at survey — no upsell if it's not needed. What colours are available?+White, black, anthracite grey and brown as standard. Samples at survey. Do you fit downpipes to a soakaway?+Yes, if a soakaway is present or new gulley connections are needed we'll include it in the quote. Is scaffolding needed?+Not usually for gutter and bargeboard on a standard two-storey house — ladders and edge protection are enough. Access cost is always included in the fixed quote. Is the work guaranteed?+Yes — 10-year workmanship guarantee from GNB Flat Roofing, plus manufacturer product warranty on the UPVC. Do you cover the whole of Norfolk, Suffolk & Cambridgeshire?+Yes. We're based in Norwich (NR5) and work across Norfolk, Suffolk and Cambridgeshire — including all the Norwich suburbs (Thorpe St Andrew, Sprowston, Hellesdon, Costessey, Taverham, Drayton, Cringleford), Wymondham, Dereham, Thetford, Great Yarmouth and King's Lynn. If you're on the edge of that area, phone and ask — we don't charge to travel to quote. Do you charge call-out fees?+No. Surveys and quotes are free, and there are no call-out fees. You get a fixed written price before any work starts — no day-rates, no hidden extras. Who will I actually deal with?+Neil, the owner, personally quotes and runs every job. You won't be handed to a call centre or a subcontracted crew. One point of contact from first call to final sign-off.
