About our gutter sealing in Castle Kennedy
We don’t replace gutters, fascias or roofs. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. If you are dealing with garage door frames letting rain in and fascia boards with gaps between them, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Castle Kennedy depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Gutter sealing in Castle Kennedy: local notes
Castle Kennedy 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. 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.
Homes close to Old Parish Church and Burial-ground include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why it’s worth doing now in Castle Kennedy
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A gutter length that has split
- Brackets that have snapped or loosened
- Problems with the roof covering

What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. The work usually takes a few hours, depending on the number of joints and the access. Outside jobs in Castle Kennedy need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by tracing the leak and checking the gutter itself is sound.
- 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.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
Roofline trims
We reseal trim joints with an exterior sealant.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Common problems we fix in Castle Kennedy
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
The most common problems we see are:
- Failed sealant on a garage door frame
- Damp on an inside wall under a dripping gutter
- Open joints in fascias and soffits
- Water dripping where gutter sections meet
Letting a property close to Stranraer station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Look at the gutters while it’s raining
- Keep an eye out for wet patches below a joint
- Keep ladders off the guttering
- Keep downpipes clear
Leave the new sealant to cure as we advise and avoid disturbing it.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.
Castle Kennedy questions
Will you come out to Castle Kennedy?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Castle Kennedy affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.
Can you fit new guttering?
No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We’ll confirm the access for higher gutters before we book.
How much does gutter sealing cost in Castle Kennedy?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Other services in Castle Kennedy
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again.
