Honest advice

Do You Actually Need Velux & Roof Windows?

Roof-window problems are usually leaks around the flashing kit, failed seals letting in draughts or condensation, or an old unit due for replacement.

Water tracking in around the window frame after rain
Draughts or condensation between the panes
A rattling, ill-fitting or seized-up old unit
Wanting to add light to a loft or extension

When it is not the answer: If only the flashing kit has failed, re-flashing the existing window is cheaper than a new unit. Read the full guide.

Skylight Repair in Llandudno

Skylight Repair Specialists in Llandudno

Leaking skylights are one of the most mis-diagnosed roof problems. Most contractors replace the window when the problem is the flashing. We diagnose the actual cause before quoting — you pay only for what is actually broken.

The Flashing Problem

Velux and other roof window brands supply specific flashing kits designed for different roof coverings — there is a different kit for plain tile, profiled tile, slate and low-pitch applications. If the wrong kit was installed, the flashing cannot properly integrate with the roof covering and will admit water. This is the most common cause of leaking skylights we repair in Llandudno.

The Salt Air Factor

Llandudno's coastal salt air accelerates degradation of foam compression seals within skylight flashing surrounds. On exposed North Shore promenade and Craig-y-Don seafront properties, these seals may need replacement after 10-15 years rather than the 20+ years expected inland.

What We Repair

Flashing kit replacement (wrong specification or failed), foam seal replacement, glass unit replacement for condensation between panes, frame damage repair, operating mechanism repair and full window replacement where required. We carry parts for Velux, FAKRO, RoofLite and Dakea windows.

Roof windows on Llandudno homes face the full force of wind-driven rain off the sea, and that is exactly the condition that finds any weakness in how a window was flashed and fitted. The overwhelming majority of roof-window leaks we are called to are not the glazing unit failing — they are the flashing kit: the wrong kit for the covering, a kit not dressed properly into the surrounding slates or tiles, or seals that have perished with age and UV. So the first thing we do is establish whether you actually need a new window or simply a proper re-flash of the existing one, because a re-flash is a fraction of the cost of a replacement unit and, done correctly, solves the leak for good.

Where the unit itself has genuinely failed — misted double glazing, a seized or cracked frame — we replace like-for-like and dress the new flashing kit correctly for your covering, checking the internal reveal and seals so you are not left with a cold draught in the next gale.

If you are weighing up repairing an old roof window versus replacing it, the deciding factors are usually the glazing and the frame. A window that leaks around the outside but is sound in itself needs a re-flash, not a new unit — a fraction of the cost. A window with misted double glazing, a seized handle or a cracked, distorted frame has reached the end of its life and is worth replacing with a modern, better-sealed unit that will cope with Llandudno's wind-driven rain. We will give you the honest comparison rather than defaulting to the more expensive replacement.

Whichever route is right for your roof window — a re-flash or a full replacement — we keep the opening weathertight throughout, water-test the finished job, and make good the internal reveal where that is part of the work, so you are left with a window that is dry, draught-free and properly finished inside and out.

Customer Reviews

What Our Customers Say

★★★★★

"Velux had been leaking since installation by another contractor. Wrong flashing kit fitted. These guys identified it, fitted the correct EDL system for slate. Dry since."

Karen L. · Bodafon Road, Craig-y-Don

★★★★★

"Two Velux windows installed into Penrhyn slate on our Victorian terrace loft conversion. Correct EDL flashing kit, slates relaid neatly. No leaks and looks right for the property."

Sarah T. · Charlton Street, Llandudno

★★★★★

"Skylight fogging between panes — they correctly identified it as a failed glass unit seal, not a flashing issue. Glass unit replaced, problem resolved, no unnecessary cost."

Access

Access, Scaffolding & Permits in Llandudno

Roof-window work runs from a tower or scaffold depending on pitch and height, plus internal access to the loft. Scaffold is specified for: first-floor and steep-pitch installs where safe external standing is needed - always itemised in your written quote, never a hidden extra, and we arrange it.

Victorian and Edwardian terraces around Craig-y-Don and the town centre often mean rear-access scaffold and permit-controlled pavement space near the promenade. Pavement scaffold and skip permits go through Conwy County Borough Council; allow a few working days on streets like Mostyn Street, Madoc Street, Builder Street where space is tight.

Good to know

What It Is Like While We Work

Some internal dust where the opening is formed — we sheet the room below; external work needs only agreed access. You do not need to stay home for external work - we just need power and access agreed in advance.

We only open a roof for a window in a dry window and keep it covered between stages. Salt-laden Irish Sea wind off the Great Orme drives rain into west-facing elevations and speeds corrosion of fixings.

FAQ

Frequently Asked Questions

In over 90% of cases, the cause is the flashing, not the window itself. The most common failures are: incorrect flashing kit for the roof covering type, failed or missing soaker under the flashing, or degraded foam seals within the flashing surround.

Leaking Velux flashing repair: £200–£500 — usually a single day's work. Frame seal or glass unit failure: £300–£700. Free written diagnosis and quote before starting any work.

Yes — a slow leak at a skylight can saturate insulation and roof deck below the window, leading to timber rot in surrounding rafters and boarding. We always inspect the surrounding structure during skylight repairs.

Condensation between glazed panes indicates a failed glass unit seal — not a roof leak. The remedy is glass unit replacement, not roof repair.

If the frame is structurally sound and the leak is from the flashing or unit seal, repair or replacement of the specific component is cost-effective. If the frame is cracked or deformed, full window replacement may be more economic. We assess this on the free survey.

Yes — we work with all major roof window brands including FAKRO, RoofLite, Dakea and own-brand installations.

A straightforward flashing repair: 3-5 hours including scaffold. Glass unit replacement: 1-2 hours on site. Full window replacement: 4-6 hours. We aim to complete all skylight work in a single visit.
