Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
About our gutter sealing in Queensbury
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints and it cannot mend broken brackets, split sections or blocked downpipes. Typical jobs include water running down the wall below the gutter and earlier gutter repairs that have peeled off, across gutter end caps, roofline trims and garage door frames.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Queensbury, it’s worth checking who is responsible for the outside before booking.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Preparing for the visit

Advice
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we cannot put right
To be straight with you, some problems need a different trade:
- Problems with the roof covering
- Rotten or damaged fascia boards
- Sagging gutters or broken brackets
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

Queensbury questions
I let a flat near Kenton station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is parking a problem for a job in Queensbury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Will sealant fix a dripping gutter joint?
In many cases, yes. Cleaning, drying and resealing the joint usually works. A split or warped section needs replacing.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
How much does gutter sealing cost in Queensbury?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Are you insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
What gutter sealing looks like in Queensbury
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Headstone Manor (about 2.7 miles west) nearby, there’s older building stock in the area around Queensbury as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to All Saints Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Queensbury is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you let a flat or house near Kenton station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

How we quote for gutter sealing
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The number of rooms or windows
- Working hours on commercial sites
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
- Whether it’s a home or a business
- Where the job is, and your postcode
- Photos by email, if that is easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Don’t lean ladders against the gutter itself
- Keep downpipes clear
- Sort out a dripping joint early
- Check fascia and soffit joints for gaps
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.
Why it’s worth doing now in Queensbury
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Queensbury.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
