Gutter sealing in Swanbourne
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s all about the joints rather than new guttering. We work on uPVC fascias, gutter joints and roofline trims, and the jobs we see most are old gutter sealant that has let go and trim joints where the sealant has failed.
Older homes in small places like Swanbourne may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What gutter sealing looks like in Swanbourne
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Swithun, an extension built onto an older house moves differently, and the joint between them takes the strain.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Watch the wall under the gutters for staining
- Make sure downpipes aren’t blocked
- Watch for drips in a downpour
- Keep the gutters clear of debris
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
Questions from Swanbourne
Will you come out to Swanbourne?
Yes. Swanbourne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Swanbourne in your area for gutter sealing?
Yes. We work across London and the South East, and Swanbourne is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you replace gutters or fascias?
No. We seal leaking joints, end caps and trims. Replacement needs a gutter installer or roofer.
What about gutters on a second or third storey?
Low-level work is easiest. We will confirm the access for higher gutters once we know more.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Related advice
Leave it or put it right?
Replacing fascias because of open joints is generally unnecessary. A neat seal closes the gaps as long as the boards are in good condition. Where a wall is exposed, as many are in small places like Swanbourne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
