Guide ranges. The first visit is charged and priced before booking; any new glass is priced in writing before work starts. Scaffold, access towers or a crane are priced separately if the job needs them, and building warrant fees, where a job needs them, are shown as their own line.
Where our fitters travel
Distance is rarely the deciding factor. A roof in Barrhead, 3 miles from Paisley, gets the same survey, the same written quote and the same fitting process as one in PA2, PA1 and PA3. What changes the price is the job itself: size of unit, roof type, access and lifting. Renfrew, around 3 miles out, is treated the same way.
Included in the work
- Measuring visit to size the glass and identify its make-up
- Old glass taken out safely and removed from site
- New glazing tapes, gaskets or sealant fitted to suit the frame
- Condensation or a failed seal — We confirm whether the mist is inside the sealed unit or on the room-side surface.
- Condition of the frame — We look at the frame closely before committing to new glass.
How the glass is replaced
The second visit is the quick one. With the new unit made to size, the fitters take the old glass out, check the frame and drainage paths, and set the new glass on packers so it sits square and drains properly. Seals and cappings are renewed where needed, the area is cleared, and you are shown what was done.
Planning and building rules in Scotland
In Scotland, forming a new rooflight opening needs a building warrant from the council, because the roof is being altered. Replacing an existing rooflight complete with its frame doesn't need a warrant, but the new unit still has to meet the building standards, including the 1.6 W/m²K energy figure for windows and rooflights in alterations. Planning depends on the house and where it is: householder permitted development rights don't apply in conservation areas, and listed buildings need consent. We confirm this with you before quoting.
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 Paisley
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.
How long does new rooflight glass take?
The new sealed unit is made to the measured size, so there is a gap between the measuring visit and the fitting visit while it is produced. We give you the expected timing when we price the glass, and book the fitting once it has arrived.
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.
Send photos of the problem in Paisley and we will price the visit before you book it.
