Gutter, fascia & soffit sealing in Bickley, Greater London
Gutter and fascia joints in Bickley need attention? We remove the old material, prepare the joints and seal them properly.
- Open joints in fascias and soffits
- Cracked sealant along roofline trims
- Damp on an inside wall under a dripping gutter
Outside joints around Bickley
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
If you let a flat or house near Bickley station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near Church of St George, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we handle gutter sealing in Bickley
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 is broken or sagging, we’ll tell you. We work on roofline trims, gutter joints and garage door frames, and common reasons people get in touch are quick sealant fixes on gutters that didn’t last and cracked sealant along roofline trims.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Bickley, tell us how high the joints are and how to reach the back of the building.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Watch the wall under the gutters for staining
- Keep ladders off the guttering
- Glance at the soffit joints now and then
- Get leaks sealed before the wet months
Give the sealant the cure time we tell you before poking or cleaning near it.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
How we quote for gutter sealing
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- The size of the job
- The product the joint needs
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
What to tell us when you ask for a quote:
- How we’d reach the joints
- Whether it has been sealed before
- The problem you’ve noticed
- A few pictures by email, if you can

What we are called out for in Bickley
When a gutter sags, its joints open. Resealing a sagging joint will not last, so the gutter needs refixing first.
Most people get in touch after spotting one of these:
- Damp on an inside wall under a dripping gutter
- Quick sealant fixes on gutters that didn’t last
- Drips from gutter joints and end caps
- Old sealant on roofline trims that has split
Schools such as Bullers Wood School for Boys are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a few hours and we leave things clean and tidy. For a job in Bickley, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we find the drip and check the gutter is not cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.
Getting ready for the visit
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

What happens if it’s left?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Bickley, the repair is bigger than a sealant job.
Instead of a standard rate, 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.

Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Is it possible to stop a gutter joint dripping with sealant?
Yes, as long as the gutter itself is in good order. The joint is cleaned and dried first so the seal holds.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We’ll confirm the access for higher gutters before we book.
Where are you based?
We work from Crawley. We cover Bickley and the rest of Greater London, along with the rest of our area.
Will you clear out my gutters?
We clear debris around the joints we’re sealing. Full gutter cleaning is a separate job.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
