Rooflight glass replacement in Prestatyn

A misted or cracked rooflight does not always need a whole new unit. If the frame is sound and the seals around it are dry, we can often measure for a new sealed glass unit and fit it into the existing frame in Prestatyn. The first visit is to measure and check the frame, which is charged, with the price confirmed before you book. The new glass is then made to size, and a second visit fits it. If the frame itself has failed, we tell you that a replacement rooflight makes more sense.

Is your address covered?

Prestatyn and the districts around it, LL19, LL18 and LL17, all sit inside our working area. So does the ground between Prestatyn and Rhyl (4 miles), and on towards Flint (13 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What we do on the day

  • Joints water tested and the glass cleaned inside and out
  • Sealed unit ordered to match or improve on the original glass
  • Frame rebate cleaned and checked for damage, corrosion or failed seals
  • Can the glass come out? — We check whether your rooflight has removable glass or a bonded unit before booking a fitting visit.
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.

How the glass is replaced

On the fitting visit, the room below is protected first. The beads or cappings come off, the old unit is lifted out with suction lifters, and the rebate is cleaned and checked for damage or blocked drainage. The new sealed unit goes in on fresh packers and gaskets, the cappings are refitted and sealed, and the glass is cleaned. Most glass swaps take half a day once the new glass is made.

Planning and building rules in Wales

For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.

What to send us

Photos of the problem glass from inside and out, a rough width and length, and whether the rooflight opens or is fixed are enough to price the first visit. Add the postcode and how the roof is reached, and tell us if more than one unit has misted.

Common questions in Prestatyn

Can you replace just the glass in my rooflight?

Often, yes. If the frame, gaskets and drainage are sound, a new sealed unit can go into the existing frame. If the frame has failed, is distorted or leaks around the edge, replacing the whole rooflight is usually the better answer, and we tell you that.

Is the measuring visit charged?

Yes. The first visit measures the existing glass and checks the frame, and it is charged. We confirm that price before you book. The fitting of the new glass is then priced in writing, so you see the full cost before anything is ordered.

Can I upgrade the glass while it is being replaced?

Usually. Solar-control, self-cleaning, toughened or laminated glass can be specified as long as the frame can take the thickness and weight. We check that on the measuring visit and price the options side by side.
