About our gutter sealing in Longformacus
Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed with an exterior sealant. Common call-outs are for wet patches on the wall under a gutter joint and failed sealant on a garage door frame, on gutter end caps, roofline trims 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.
Every job comes with a one-year guarantee.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Glance at the soffit joints now and then
- Get leaks sealed before the wet months
- Rest ladders on the wall, not the gutter
- Clean out the gutters once or twice a year
Give the sealant the cure time we tell you and avoid disturbing it.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
Surface by surface
Gutter end caps
Drips from a stop end run down the brickwork. It’s a quick reseal.
Garage door frames
A fresh seal around the frame stops rain getting in.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Blocked downpipes
- Rotten or damaged fascia boards
- Leaks from the roof rather than a joint
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

FAQs for Longformacus
Do you cover smaller places like Longformacus?
Yes. Longformacus is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with gutter sealing in Longformacus?
All our work, in Longformacus and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Do you replace gutters or fascias?
No. Our work is sealing joints and replacement is a job for an installer.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Is sealant enough for a gutter that has dropped?
Sealing a sagging joint will not last. The gutter needs refixing by a gutter installer.
The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes an hour or two for a few joints, longer for a full run.

- The joints are checked once sealed.

Why act early in Longformacus
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. In an older home around Longformacus, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why book with us
- We agree the colour with you first
- Neat joints and a tidy finish

Walls and rooflines in Longformacus
Harled (roughcast) walls are common in Scotland, 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 failed outside joints work against that.
For an older house near a landmark such as Longformacus Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
