Sun tunnel installation in Dronfield

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for sun tunnel installation in Dronfield, internal finishing is listed so you can see whether it is included or left for your decorator. That way a sun tunnel looks right from the room below as well as from outside. We cover Dronfield and properties throughout Derbyshire.

Areas around Dronfield we cover

Dronfield and the districts around it, S18, S41 and S40, all sit inside our working area. So does the ground between Dronfield and Chesterfield (4 miles), and on towards Fulwood (5 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.

Fit-only or supply and fit

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a sun tunnel on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

On the day, we cover

  • Ceiling opening cut neatly and the diffuser fitted
  • Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
  • Rigid or flexible tube run and joined, with as few bends as possible
  • Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
  • Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.

Fitting your sun tunnel, step by step

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a sun tunnel runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Regulations for Dronfield properties

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Getting a price from photos

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 S18, and we can price it.

Common questions in Dronfield

What if my roof opening is the wrong size for the sun tunnel?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

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.
