Gutter sealing for homes and businesses in Upton
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. If you have earlier gutter repairs that have peeled off and gaps along fascia and soffit joints, we can put it right, on soffit joints, uPVC fascias and gutter joints alike.
Homes around Upton range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
All of our work is guaranteed for twelve months, in Upton and everywhere else we cover.

Upton questions
Do you cover smaller places like Upton?
Yes, Upton is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Slough station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. A full gutter clean is a separate job.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What should I tell you?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where is Mr Mastic based?
We work from Crawley. We cover Upton and the rest of Slough, along with the rest of our area.
Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before work begins.
Outside joints around Upton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Windsor Castle (about 1.5 miles south-west) are a reminder that the area around Upton has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Slough station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Schools such as St Mary's Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Local landmarks in Upton
Typical jobs here are in homes near The Red Cow Public House, Upton Court Grammar School and Long Close School. For rail, the closest station is Slough station, roughly 0.6 miles north. A little further out are Windsor Castle (1.5 miles south-west) and Museum of Eton Life (1.2 miles south-west). Not far away are Stoke Common and Taplow Lake.
Looking after it afterwards
Looking after new joints is easy:
- Keep the gutters clear of debris
- Look for streaks or damp on the wall below gutters
- Have sagging gutters refixed early
- Watch for drips in a downpour
Keep the gutters clear of leaves and moss, so water drains away past the joints. Standing water strains every seal.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry.
Why it’s worth doing now in Upton
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. Around Upton, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What we are called out for in Upton
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and drips through.
Common reasons people contact us are:
- Quick sealant fixes on gutters that didn’t last
- Streaks down the brickwork from a leaking joint
- Trim joints where the sealant has failed
- Dripping gutter ends
If you live in an older home near Church of St Laurence, older walls, gutters and the joints where extensions meet them need a flexible sealant.

- The problem you’ve noticed
- The type of property

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes an hour or two for a few joints, longer for a full run for a typical job. Parking around Upton is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Getting ready for the visit
