Exterior cladding

Faded paint, patchy render or tired timber boards can make a home look older than it is. Exterior cladding is a fast, clean way to refresh those elevations: crisp lines, consistent colour and almost no upkeep.

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

We design and install uPVC cladding for houses, dormers and gable peaks, specifying breathable build-ups and neat trims so the finish looks like it belongs — and keeps its good looks through years of Welsh weather.

A lasting result is about the whole system: ventilated battens, membranes where appropriate, tidy starter profiles, carefully mitred corners and colour-matched trims. Get those details right and your house cladding won’t just look smart on day one; it will stay straight, quiet and weather-tight for the long term.

What is uPVC cladding — and how is it built?

UPVC cladding boards interlock horizontally (or vertically with specific systems) and sit on treated timber or composite battens. Behind the boards we plan for:

  • Drainage and ventilation: a ventilated cavity so any moisture can escape.
  • Breathability: appropriate membranes in exposed locations to keep water out while allowing vapour to pass.
  • Starter and edge profiles: straight lines from the first course, with crisp corners and window reveals.
  • Fixings: corrosion-resistant screws at the right centres, allowing for seasonal movement.

The result is a stable, good-looking façade that’s easy to live with.

Where cladding makes the biggest visual impact

  • Dormers: brighten ageing roof additions with sharp, consistent lines.
  • Gable peaks and apexes: define the silhouette and tidy failing paint or render.
  • First-floor bands over bays: unify mismatched repairs and add modern contrast.
  • Side returns and extensions: provide a clean, resilient finish where brick or render struggles.
  • Porches and entrances: pair with new doors for a coherent welcome.

We’ll sketch options to show how exterior cladding balances your elevations.

External wall cladding uPVC vs timber and fibre-cement

  • External wall cladding uPVC: light, low-maintenance, colour-stable and cost-effective with quick installation.
  • Timber: beautiful and natural, but higher upkeep (painting/oiling cycles).
  • Fibre-cement/plank systems: robust and crisp; heavier and usually costlier to install.

If your priority is durable, tidy and easy-care, modern uPVC is hard to beat. We’ll bring samples so you can compare textures and colours in daylight.

Styles, colours and grains that suit your home

  • Colours: White and Cream for timeless brightness; Anthracite and Slate for contemporary contrast; soft heritage tones for traditional streets.
  • Wood-effect foils: Golden Oak, Rosewood, Irish Oak — the look of timber without the maintenance.
  • Board styles: shiplap and open-V profiles for horizontal runs; specialist ranges for vertical emphasis.
  • Detail trims: colour-matched corners, end caps, starter bars and window reveals for a “factory neat” finish.

We coordinate cladding with window frames, fascias and doors so everything reads as one design.

Breathability and moisture management — the science bit done simply

Cladding must shed rain and let the wall system dry. We ensure:

  • Ventilated cavities at base and top to promote airflow.
  • Breather membranes (where appropriate) that stop driven rain yet allow vapour to escape.
  • Drip details and stop profiles that guide water out, not into the wall.
  • Clear eaves ventilation so roof and wall systems don’t fight each other.

These quiet details keep boards straight, walls dry and paint flake firmly in your past.

Pairing cladding with roofline and windows

Cladding projects often dovetail with other upgrades:

  • Replace or colour-match fascias, soffits and guttering for a crisp roof edge.
  • Coordinate with uPVC windows or composite doors so grains and tones align.
  • Add porches or canopies with trims that tie cleanly into the new façade.

One coherent scheme is more convincing (and often better value) than piecemeal patches.

Installation standards — where straight lines stay straight

Our method as cladding installers focuses on long-term crispness:

  • Survey and setting-out: laser levels and chalk lines to plan perfectly level courses.
  • Substrate prep: check fix integrity; pack or replace uneven areas so boards don’t telegraph bumps.
  • Battens & membranes: treated battens at correct centres; breathable layers in exposed zones.
  • Fixing and movement: corrosion-resistant screws, correct expansion gaps and tidy mitres.
  • Corners & reveals: purpose-made trims cut cleanly, sealed neatly and aligned to window lines.
  • Final clean-down: boards washed, swarf removed, and edges sighted from street distance.

It’s how we make the finish look “built with the house”.

Cladding on dormers and tricky junctions

Complex areas are where poor jobs fail first. We:

  • Form box-end details that shed water, not trap it.
  • Tie into lead flashings and roof membranes without compromising ventilation.
  • Step boards around soil pipes and cables with snug collars and tidy seal lines.
  • Use proportionate trims so small dormers don’t look over-framed.

Function first, then finesse — both matter.

Maintenance — little effort, long life

  • Wash with mild soapy water once or twice a year; no abrasives.
  • Rinse off algae early (easier when fresh, especially on north elevations).
  • Keep climbers off boards; they trap moisture and mark finishes.
  • After storms, glance at corners and terminations — re-clip anything that’s crept.

Expect many years of sharp looks from modern uPVC cladding with these five-minute habits.

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.

From initial call from Sureseal making appointments to choosing our windows all the team have been very knowledgeable and helpful, No big sell to get the costs up just what we wanted and even reduced aspects no of closers etc. to meet requirements. Plenty of payment options with full explanation again no push either way. Survey was again very straightforward and with some discussion even more savings found. Pleasure to do business with. Great service and very knowledgeable.will post photos of finished project once complete. Mike Hedges

Questions

Your questions, answered

Will cladding trap damp in my walls?

Not when detailed correctly. Ventilated cavities and the right membranes allow vapour to escape while keeping driven rain out.

Can cladding go straight over existing timber?

Only if the timber is sound, straight and dry. We usually recommend battens and a ventilated cavity for longevity and neatness.

How durable are wood-effect foils?

Modern foils are UV-stable and bonded for long life. Clean with mild solution only.

Does uPVC look ‘plasticky’?

Quality boards with subtle grains look crisp and convincing, especially when trims are colour-matched and lines are kept true.

Can you match my window and fascia colours?

Yes — we coordinate cladding shades with window frames, fascias and soffits, and doors for a coherent elevation.
