How we handle gutter sealing in Castlecary
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first, then dry the joint before sealing. We’re often asked to deal with end caps that drip every time it rains and garage door frames letting rain in, across gutter end caps, gutter joints and uPVC fascias.
Outside joints can only be sealed when they’re dry, so work in Castlecary depends on the weather. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months.

What gutter sealing looks like in Castlecary
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Cumbernauld station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near Haggs Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Castlecary is about 3 miles south-west of Bonnybridge, in Falkirk.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a few hours. Outside jobs in Castlecary need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First we agree which joints need sealing.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

When it isn’t the sealant

Do you need gutter sealing in Castlecary?
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
Most people get in touch when they notice one of these:
- Trim joints where the sealant has failed
- End caps that drip every time it rains
- Rain getting in around a garage door
- Open joints in fascias and soffits
Managing a site like Abronhill High School? Then its movement joints, gutters and trims need looking after like any other building’s.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t lean ladders against the gutter itself
- Check that water runs out of the downpipes
- Check the gutters during heavy rain
- Keep the gutters clear of debris
Check the joints after heavy rain. It’s the easiest time to see a leak.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp.

How we quote for gutter sealing
We quote each job individually. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Any mould that needs treating
- The number and length of the joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
What the job involves on each surface
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
Gutter joints
When a joint drips, the gutter is often still sound. Resealing is normally enough.
Why deal with it now?
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
