Guttering

Good guttering is quiet, steady and almost invisible in day-to-day life — until it fails. Then you see drips over doorways, streaks on brickwork and puddles where water should never sit.

Roofline products: white fascia, soffit and guttering on a brick house

We supply and fit guttering that’s correctly sized, set to the right falls and colour-matched to your roofline, with secure joints and tidy downpipes that move the heaviest rain away from your home. Whether you need a short gutter replacement over a porch or a full run around complex roofs and dormers, our gutter installers work safely and cleanly, leaving you with a system that just works.

Signs it’s time for gutter replacement

  • Drips from joints or corners even after resealing
  • Gutters that hold water (no fall) or overflow in modest rain
  • Black staining or moss tracks on brickwork below the eaves
  • Loose brackets, sagging runs or discoloured, brittle plastic
  • Downpipes that back up or discharge at the base of walls

If two or more apply, planned gutter replacement is safer (and cheaper long-term) than another round of mastic and hope.

Choosing the right profile and material

  • UPVC guttering (most popular): durable, low-maintenance and cost-effective with quick, clean installation. Available in half-round, square and deep-flow profiles, plus colours to match your fascias.
  • Deep-flow profiles: higher capacity for large or steep roofs; ideal for valleys and long runs where stormwater peaks quickly.
  • Colour choices: White, Black, Anthracite Grey and Browns, with matching downpipes, shoes and bends for a consistent finish.

We size capacity to your roof area and rainfall exposure, not guesswork.

Getting the falls right — small angles, big difference

A “flat” gutter won’t drain. We set subtle, consistent falls towards outlets (usually 1:600 to 1:350 depending on run length and profile), check them with a level and sightline, then test with water. Correct fall + correct outlet placement = quiet performance in heavy rain.

Leak-free joints and corners — built to be serviceable

We use manufacturer-approved, compression-sealed unions and corners rather than relying on blobs of silicone. Benefits:

  • Movement-tolerant during hot/cold cycles
  • Easy to service or replace in future
  • Cleaner look with factory-neat seals

On older properties where walls wander, we adjust bracket spacing to keep joints stress-free.

Downpipes — where the water actually leaves

Downpipes are the last mile. We:

  • Position outlets to avoid long “flat” runs that invite puddling.
  • Fix downpipes on proper centres so they don’t tap or rattle.
  • Route to gullies or soakaways sensibly, adding swan-necks and bends where needed without creating choke points.
  • Finish with colour-matched shoes or hopper heads that look deliberate, not improvised.

If your drains are sensitive, we’ll suggest leaf guards or easy-clean strainers.

Pairing guttering with fascias and soffits

Gutters only run true when they’re fixed to sound fascia boards. If your fascias are soft or wavy, we’ll price options to renew them at the same time. We can also colour-match new gutters to existing fascias and soffits for a joined-up look.

New gutters over conservatories, dormers and tricky junctions

The awkward bits are where poor jobs fail first. We handle:

  • Box ends that shed water properly instead of trapping it
  • Valley discharge into deep-flow profiles to swallow peak flows
  • Conservatory over-sails with purpose-made covers and careful sequencing
  • Dormer tie-ins with crisp trims and correctly set mini-gutters

It’s the difference between “it’ll do” and “that looks built with the house”.

Leaf, moss and debris control — prevention beats cure

  • Balloon guards or wire strainers at outlets to stop leaf clumps travelling down the pipe
  • Leaf-guard meshes on tree-heavy plots (we’ll advise where they genuinely help)
  • Downpipe access points for quick rodding without dismantling

We’ll be honest: not every home needs guards. Sometimes a quick post-autumn clean is the simpler, better solution.

Maintenance — five-minute habits that add years

  • Clear leaves after autumn and again in spring if trees are near.
  • Check joints and corners after big storms; re-clip if anything has crept.
  • Keep downpipe gullies free of grit so they don’t back up.
  • Rinse algae streaks off façades early — it’s easier when fresh.
  • If you hear rattling, a single loose bracket could be the culprit — call us before it worsens.

We had our windows and doors replaced by Sureseal Windows and could not be happier. We had a home visit from the salesman, who went through the various designs and colours available plus an initial measurement of all the items needed. Following our agreement to purchase the doors and windows a supervisor visited to precisely measure the openings and look for any issues that might arise during the install. The fitting was booked in about 10 weeks later. Alan contacted us to give his ETA of the morning of the start of the job. And we cannot praise Alan enough for his work and cleaning up after. All areas where work was done were covered with dust sheets and no mess was left. There were a couple of remedial jobs to be completed when the parts were available. Sean completed these jobs for us over a coarse of a morning. And, as with Alan previously Sean's work was great and all was cleaned up on completion. Both workers are a credit to SureSeal. And we highly recommend the Company.

Questions

Your questions, answered

Do new gutters always need new fascias?

Not always. If boards are straight and sound, we can refit to them. If they’re soft or wavy, new gutters won’t stay true — we’ll advise honestly.

Will deep-flow look bulky on my house?

Deep-flow profiles are only slightly taller but handle much more water. On most homes, especially with two storeys, they look perfectly proportioned.

Can you match my window colour?How often should gutters be cleaned?

Yes. uPVC guttering is available in popular colours, including Anthracite Grey and Black, to coordinate with windows, doors and fascias.

How often should gutters be cleaned?

Typically once a year; twice if you’re under trees. We can schedule a maintenance visit if you prefer.

What causes constant dripping at one joint?

Usually poor fall or a stressed union. We reset the bracket line and replace the joint with a compression-sealed fitting.
