About our gutter sealing in Crawfordjohn
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. Typical jobs include old sealant on roofline trims that has split and water running down the wall below the gutter, across gutter end caps, garage door frames and soffit joints.
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.
All of our work is guaranteed for twelve months, in Crawfordjohn and everywhere else we cover.

Common problems we fix in Crawfordjohn
Gutter joints depend on seals that wear out. Temperature changes make gutters move and that movement opens up tired joints.
It’s worth asking for a quote if you see:
- Old gutter sealant that has let go
- Open joints in fascias and soffits
- Damp patches inside below a leaking gutter
- Old sealant on roofline trims that has split
In and around Crawfordjohn, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
- How long to leave it before use
Surface by surface
Garage door frames
The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
Soffit joints
Soffits sit under the eaves, where joints can open up. We seal them to close the gaps.
What gutter sealing looks like in Crawfordjohn
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you live in an older home near Crawfordjohn Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

How we quote for gutter sealing
There’s no set price list, because jobs vary so much. What we look at:
- Access and height
- The amount of work
- The product the joint needs
- Any working-time requirements on site
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- How many joints, rooms or windows are involved
- The address or postcode of the job
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, drop us a line at info@mrmastic.co.uk.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Get a dropping gutter looked at quickly
- Glance at the soffit joints now and then
- Sort out a dripping joint early
- Make sure downpipes are not blocked
Have a look at the gutter during a downpour now and then. Drips are easiest to spot while it’s raining.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.

Is sealant enough for a gutter that has dropped?
Not for long. The joint will pull apart, so the fall and brackets need sorting first.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. The gaps are cleaned and sealed neatly with a suitable exterior sealant.
Do you work on high-level gutters?
It depends on the access. Tell us the height and what’s around the gutter and we’ll confirm what’s needed.
Do you work for landlords and businesses?

How long does the job take?

Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
