How we handle gutter sealing in Brasted
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. We work on garage door frames, roofline trims and soffit joints, and the jobs we see most are rain getting in around a garage door and leaking gutter joints and stop ends.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Brasted, it’s worth checking who is responsible for the outside before booking.
Our work is backed for twelve months.

Signs you need gutter sealing in Brasted
A sealant applied to a damp or dirty joint will not bond. Rushed repairs often don’t last long for this reason.
The most common problems we see are:
- Leaking gutter joints and stop ends
- Failed sealant on a garage door frame
- Quick sealant fixes on gutters that didn’t last
- Water running down the wall below the gutter
Schools such as Combe Bank School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Outside joints around Brasted
With historic houses such as Quebec House (about 1.5 miles south-west) nearby, there’s older building stock in the area around Brasted 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.
For an older house near a landmark such as Church of St Martin, an extension built onto an older house moves differently, and the joint between them takes the strain. Brasted is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How to look after the new joints
So the new joints stay in good condition:
- Keep the gutters clear of debris
- Glance at the soffit joints now and then
- Check the gutters during heavy rain
- Keep ladders off the guttering
Give the sealant the cure time we tell you and avoid disturbing it.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.

What else we do in Brasted
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Landlord and commercial work in Brasted
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes an hour or two for a few joints, longer for a full run, and the area is left clean. For a job in Brasted, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

FAQs for Brasted
Do you work for landlords with property near Dunton Green station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Can parking be tricky for a visit in Brasted?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
