How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from an hour or two to a few hours for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- The sealant is applied and finished.
- We check our work before we leave.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

How we handle gutter sealing in High Blantyre
Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed using a sealant made for outdoor use. We’re often asked to deal with internal damp traced to a gutter joint and open joints in fascias and soffits, on uPVC fascias, gutter joints and garage door frames.
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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Do you hold any approvals?

How do I get a quote for gutter sealing in High Blantyre?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Leave it or put it right?
New gutters cost far more than a few resealed joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it has failed, we’ll tell you. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What you get with us
- White, clear, grey or another colour, product permitting
- Colour picked to suit the job
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator

Can I do it myself?
Not every job suits DIY: 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’ve already had a go yourself, that’s fine. We cut it out and start again.
Walls and rooflines in High Blantyre
High Blantyre is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for gutter, fascia and roofline joints to keep out. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Blantyre station, leaking gutter joints on a rental are best caught before they stain the walls. Managing a site like High Blantyre Primary? Then larger buildings have long runs of movement joint that eventually need resealing.

When to call us in High Blantyre
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
If you can see any of these, it’s time to have the joints looked at:
- Wet patches on the wall under a gutter joint
- Drips from gutter joints and end caps
- Dripping gutter ends
- Garage door frames letting rain in
If you live in an older home near Blantyre Old Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Before you book anyone
- What guarantee comes with the work
- Whether all the old sealant comes out first
- What product goes in the joint
- Is VAT in the price?
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Water backing up from a blocked pipe
- Brackets that have snapped or loosened
- Cracked, split or warped gutter sections
If you are 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
- Roofline trims
- Gutter end caps
- uPVC fascias
- Garage door frames
- Soffit joints
- Gutter joints
Keeping the joints in good condition
After the cure time, these simple habits help:
- Make sure downpipes aren’t blocked
- Keep an eye out for wet patches below a joint
- Get a dropping gutter looked at quickly
- Check fascia and soffit joints for gaps
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.
