About our gutter sealing in Datchet
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. We are often asked to deal with stop ends leaking at the end of a run and damp patches inside below a leaking gutter, on soffit joints, roofline trims and garage door frames.
Around Datchet, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Datchet: your questions answered
Do you cover smaller places like Datchet?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Datchet station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Is sealing fascia joints something you do?
We do. Our work is the joints, and if a board is damaged, we will tell you.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Datchet, along with the rest of our area.
Will sealant fix a dripping gutter joint?
Often, yes. Cleaning, drying and resealing the joint usually works. If the section is split or warped, it needs replacing.
Why it’s worth doing now in Datchet
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right before the damage spreads. Homes in smaller places like Datchet can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.

Signs you need gutter sealing in Datchet
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping so the brackets need attention first.
The problems people generally mention when they call are:
- Open joints in fascias and soffits
- Leaking gutter joints and stop ends
- Failed sealant on a garage door frame
- End caps that drip every time it rains
For an older house near a landmark such as Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep an eye out for wet patches below a joint
- Clean out the gutters once or twice a year
- Look along the fascias for open joints
- Look at the gutters while it’s raining
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
What gutter sealing looks like in Datchet
With historic houses such as Frogmore House (about 1 mile south-west) nearby, there’s older building stock in the area around Datchet as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Datchet station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you look after a building such as Datchet St Mary's CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Preparing for the visit
