About our gutter sealing in Stow
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. We work on uPVC fascias, gutter end caps and gutter joints, and people most often call us about stop ends leaking at the end of a run and failed sealant on a garage door frame.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to a few hours. Around Stow, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- The sealant is applied and finished.
- The joints are checked once sealed.
Getting ready for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

Do you need gutter sealing in Stow?
End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.
These are the problems we are asked about most:
- Old gutter sealant that has let go
- End caps that drip every time it rains
- Streaks down the brickwork from a leaking joint
- Drips from gutter joints and end caps
Homes close to St Mary's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What the job involves on each surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
Soffit joints
Soffits sit under the eaves, where joints can open up. We seal them to close the gaps.
Honest limits
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Gutters that have dropped or pulled away
- Blocked downpipes
- Boards that have decayed or split
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Gutter joints
- uPVC fascias
- Garage door frames
- Soffit joints

Outside joints around Stow
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Stow station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Aftercare tips
A little care helps the new joints last. We recommend:
- Deal with a drip before winter
- Have sagging gutters refixed early
- Rest ladders on the wall, not the gutter
- Look for streaks or damp on the wall below gutters
Give the sealant the cure time we tell you and avoid disturbing it.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
