Gutter, fascia & soffit sealing in Coldharbour, Surrey

- Old sealant on roofline trims that has split
- Streaks down the brickwork from a leaking joint
- Quick sealant fixes on gutters that didn’t last
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Gutter sealing for homes and businesses in Coldharbour
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 and the joint is dried before the new sealant goes in. We work on gutter end caps, soffit joints and gutter joints, and people most often call us about trim joints where the sealant has failed and leaking gutter joints and stop ends.
Somewhere as small as Coldharbour, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Every job is covered by our one-year guarantee.

What affects the quote in Coldharbour
Every job gets its own quote. These are the things that affect it:

How it works
There isn’t much for you to do on the day. 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 from start to finish. For a village or hamlet like Coldharbour, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention any parking rules near the property

Advice
Aftercare tips
To keep the joints looking good and working properly:
- Look along the fascias for open joints
- Look at the gutters while it’s raining
- Watch the wall under the gutters for staining
- Clean out the gutters once or twice a year
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
Your questions about gutter sealing in Coldharbour
Is Coldharbour within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Holmwood station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
Tell us what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
What does gutter sealing cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or email us and let us know what needs doing and where.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Why it’s worth doing now in Coldharbour
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 has failed, we will tell you. Around Coldharbour, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
