Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. 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.
Is your address covered?
Looking at a property near Renfrew but not quite in it? We work across PA4, PA1 and PA3 and outwards to Clydebank, Erskine and Paisley. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Renfrew.
What the job includes
- Existing vent, actuator and upstand surveyed with the specialist
- Certified vent and actuator matched to the opening and controls
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
How a fitting day runs
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a smoke vent rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days per vent.
Planning, building warrants and Renfrew
In Scotland, smoke ventilation is covered by the domestic or non-domestic Technical Handbook, depending on the building. Vents must be certified products, keep the required free area, and be connected and commissioned by a smoke-control specialist. A building warrant is needed where the system is altered.
Before you get in touch
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around PA4 and we will come back with a quote or a survey date.
Common questions in Renfrew
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
What upstand height and roof pitch does smoke vent rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
