Gutter sealing in Gunnista
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. We are often asked to deal with fascia boards with gaps between them and wet patches on the wall under a gutter joint, on gutter end caps, gutter joints and uPVC fascias.
Outside joints can only be sealed when they’re dry, so work in Gunnista depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
We stand behind the work with a one-year guarantee.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours, depending on the number of joints and the access, including the tidy-up. Around Gunnista, 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.
- First, we find the drip and check the gutter is not cracked or sagging.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant will not bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Common problems we fix in Gunnista
Sagging sections pull joints apart. Resealing a sagging joint will not last, so the gutter needs refixing first.
These are the problems we are asked about most:
- Rain getting in around a garage door
- Gaps along fascia and soffit joints
- Trim joints where the sealant has failed
- Wet patches on the wall under a gutter joint
If you live in an older home near St Ola's Church and burial-ground, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- How long the guarantee is
- Is VAT in the price?
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why

Gunnista questions
Is gutter sealing in a coastal place like Gunnista any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Gunnista within the area you cover?
Yes, Gunnista is covered. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you clean gutters?
Only around the joints we seal because the joint must be clean. Cleaning the whole run is a separate job.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. For anything higher, we’ll confirm what access is needed before we book.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Gunnista.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Water backing up from a blocked pipe
- A gutter length that has split
- Brackets that have snapped or loosened
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
What we seal
- Soffit joints
- Gutter joints
- Garage door frames
- uPVC fascias
- Gutter end caps
- Roofline trims
Why it’s worth doing now in Gunnista
You don’t need to replace a garage door because rain gets in round the frame. Sealing the frame normally stops it. In an older home around Gunnista, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why book with us
- Tidy, careful work
- Colour agreed with you before any work starts
- A sealant colour to suit the surroundings
- ARBOMaster approved applicator

Gutter sealing in Gunnista: local notes
Gunnista is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. On the islands, wind and salt spray are hard on outside sealant.
For site and facilities teams at buildings such as Anderson High School, its movement joints, gutters and trims need looking after like any other building’s.
