Sliding rooflight installation in Dorchester

What the job costs in Dorchester

Guide ranges for supply & fit. 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 control fees, where a job needs them, are shown as their own line.

Is your address covered?

Looking at a property near Dorchester but not quite in it? We work across DT1, DT2 and DT3 and outwards to Weymouth, Yeovil and Poole. 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 Dorchester.

Fit-only or supply and fit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

What the job includes

• Cable routed to the motor, ready for the electrician's final connection, quoted as a separate line
• Clear run confirmed for the glass to slide over when open
• Lifting plan for the unit, often with gear booked for the day
• Power and safety stops — We confirm the power supply and the safety features before fitting day.
• Planning for a roof terrace — We flag early whether planning may be needed for the work around the rooflight.

From arrival to clean-up

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a sliding rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Regulations for Dorchester properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

What to send for a quick quote

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in DT1, and we can price it.
