About our gutter sealing in London Colney

In and around London Colney, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

FAQs for London Colney
Is London Colney within the area you cover?
Yes, London Colney is covered. 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 Park Street station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can a leaking gutter joint be sealed?
Yes, as long as the gutter itself is in good order. The joint is cleaned and dried first so the sealant bonds.
Can you seal fascia and soffit joints?
Yes. We seal the joints, not replace the boards and we will let you know if a board has failed.
What affects the quote in London Colney
We don’t publish a price list. The quote depends on:
- Access and height
- When we can work, for business premises
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

What happens on the day
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a few hours. For a job in London Colney, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

Advice
What we can’t put right
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Guttering that needs replacing
- Boards that have decayed or split
- Blocked downpipes
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Soffit joints
- Garage door frames
- Roofline trims
- uPVC fascias
- Gutter joints
- Gutter end caps
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What the job involves on each surface
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
Roofline trims
Trims along the roofline are often finished with sealant. When it splits, water can get behind.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What gutter sealing looks like in London Colney
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Batchwood Hall (about 3.9 miles north-west) are a reminder that the area around London Colney has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Park Street station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. For site and facilities teams at buildings such as Bowmansgreen Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Keeping the joints in good condition
Aftercare is simple:
- Check fascia and soffit joints for gaps
- Don’t leave a sagging gutter
- Don’t lean ladders against the gutter itself
- Make sure downpipes aren’t blocked
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
