Gutter sealing in Castledykes from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Aftercare tips
Looking after new joints is easy:
- Keep downpipes clear
- Clear leaves and moss from the gutters
- Get leaks sealed before the wet months
- Look along the fascias for open joints
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
Gutter sealing in Castledykes
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on soffit joints, gutter joints and uPVC fascias, and people most often call us about rain getting in around a garage door and internal damp traced to a gutter joint.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee, large or small.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes anything from an hour or two to a few hours. For a place like Castledykes, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Landlords, agents and businesses in Castledykes
Letting agents and landlords in Castledykes can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What happens if it’s left?
You do not need new fascias just because the joints have opened. Sealing the joints tidies them up if the boards are sound. Around Castledykes, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

Castledykes: your questions answered
Do you cover smaller places like Castledykes?
Yes. Castledykes is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Dumfries station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Can you reach high gutters?
It depends on the access. Tell us the height and what’s around the gutter and we’ll confirm what’s needed.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What guarantee comes with the job?
Our 12-month guarantee applies to all our work.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Will sealing fix a sagging gutter?
Sealing a sagging joint will not last. The gutter needs refixing by a gutter installer, and we will tell you if that is what we find.

Signs you need gutter sealing in Castledykes
Sealant laid on a wet or dirty joint fails early. Rushed repairs often do not last long.
These are the problems we are asked about most:
- Gaps along fascia and soffit joints
- Water dripping where gutter sections meet
- Cracked sealant along roofline trims
- Garage door frames letting rain in
Schools such as Dumfries Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- What insurance they hold
- Which colour the sealant will be
- How long to leave it before use
- Whether all the old sealant comes out first
Walls and rooflines in Castledykes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. 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 Troqueer Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Dumfries station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
