Guide ranges. The first visit is charged and priced before booking; any repair is priced in writing before work starts. 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.
Coverage in and around Bletchley
Distance is rarely the deciding factor. A roof in Milton Keynes, 3 miles from Bletchley, gets the same survey, the same written quote and the same fitting process as one in MK2, MK3 and MK1. What changes the price is the job itself: size of unit, roof type, access and lifting. Leighton Buzzard, around 6 miles out, is treated the same way.
What the job includes
- Controlled water test where it helps pin down the entry point
- Failed sealant cut out, joints cleaned, dried and resealed
- Inside check of stains, frame drainage channels and the reveal
- Upstand height and condition — We measure the kerb and probe the timber for softness.
- Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
How a repair visit goes
A repair visit starts outside. The fitter looks at the roof around the unit for ponding, split membrane, loose flashing and failed sealant, then moves inside to check stains, the frame and the condensation channels. Where it helps, a controlled water test narrows down the entry point. Before leaving, they explain what they found and whether a small fix can be done within the agreed visit, or needs a separate written quote.
Planning, building control and Bletchley
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.
What to send us
Before booking a visit, send what you can: a photo of the ceiling or reveal where water shows, a photo of the rooflight from outside, the roof covering if you know it, and whether it is one rooflight or several. We use that to price the visit and to bring the right materials.
Common questions in Bletchley
Will resealing fix my leaking rooflight?
Sometimes. If the sealant has simply aged and the flashing, upstand and glass are sound, a careful reseal on a dry day can solve it. If the real problem is ponding water, a low upstand or a perished membrane, fresh sealant will only hide it for a while. We tell you which one you are dealing with before recommending any work, and quote the proper fix in writing.
Can you replace just the misted glass?
Often, yes. Misting between the panes means the sealed unit has failed, but the frame around it may be perfectly sound. Where the maker's design allows the glass to be changed, we measure the unit and fit a replacement, which costs less than a whole new rooflight. Where it does not, or the frame is also worn out, we explain why replacement is the better option.
Is it condensation or a leak?
Condensation tends to appear on cold mornings, on the inner face of the glass, and runs down the frame. A leak usually follows rain or wind from a particular direction and often stains the ceiling around the opening. Blocked condensation channels can make the two look alike. Photos and a note of when it happens help us narrow it down before the visit.
