Sun tunnel installation in Stockton-on-Tees

Builders and extension firms in Stockton-on-Tees often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a sun tunnel on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around TS18 and the neighbouring districts are welcome.

Where our fitters travel

Jobs across TS18, TS19 and TS20 are part of our normal cover for Stockton-on-Tees. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Billingham and Thornaby-on-Tees are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Buying your own, or letting us supply

If you have bought a sun tunnel yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the flashing kit and the roof pitch range. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What we do on the day

  • Tube insulated where it passes through a cold loft
  • 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 — We check whether a rigid tube will fit the route before falling back on a flexible one.
  • Tube size — We match the tube size to the room and the roof.

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 sun tunnel, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Do you need permission in Stockton-on-Tees?

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

What to send for a quick quote

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, TS18 or nearby, confirms travel.

Common questions in Stockton-on-Tees

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

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.
