How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on the number of joints and the access. Outside jobs in Sandhead need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Advice
Gutter sealing for homes and businesses in Sandhead
Gutter and fascia replacement is not our trade, and nor is roofing. Sealant fixes joints and it can’t mend broken brackets, split sections or blocked downpipes. We work on gutter joints, garage door frames and soffit joints, and common reasons people get in touch are cracked sealant along roofline trims and end caps that drip every time it rains.
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, and the guarantee is the same wherever you are.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Look along the fascias for open joints
- Check that water runs out of the downpipes
- Keep the gutters clear of debris
- Look for streaks or damp on the wall below gutters
Make sure downpipes are not blocked so the gutter can drain. Blockages push water back along the gutter.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall, which can lead to staining and damp.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Sandhead questions
Will you come out to Sandhead?
Yes. Sandhead is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect gutter sealing in Sandhead?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you replace gutters or fascias?
No. We seal leaking joints, end caps and trims. Replacement needs a gutter installer or roofer.
Is gutter cleaning part of the job?
We clear debris near the joints because the joint must be clean. Cleaning the whole run is a separate job.
How long does gutter sealing take?
Most jobs take a few hours, depending on the number of joints and the access, including the preparation. We will confirm how long when we quote.
Can you match the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before any work starts.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
