About our gutter sealing in Dartmouth Park
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where one is available. If you’re dealing with water dripping where gutter sections meet and failed sealant on a garage door frame, we can help, on gutter joints, roofline trims and uPVC fascias alike.
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. For a flat in Dartmouth Park, check the lease for who looks after the outside.
All of our work is guaranteed for twelve months.

Dartmouth Park buildings and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
Letting a property close to Gospel Oak station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Dartmouth Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Do you need gutter sealing in Dartmouth Park?
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long.
Most people get in touch when they notice something like this:
- Quick sealant fixes on gutters that didn’t last
- Old sealant on roofline trims that has split
- Drips from gutter joints and end caps
- Internal damp traced to a gutter joint
Schools such as Acland Burghley School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Before booking anyone
- Which sealant they’ll use, and why
- Whether you can choose the colour
- Is the old sealant removed completely?
- What insurance they hold

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

FAQs for Dartmouth Park
Can you do gutter sealing in Dartmouth Park?
Yes. We work across London and the South East, and Dartmouth Park is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Gospel Oak station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from an hour or two to a few hours. We’ll give you a better idea when we quote.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you fit new guttering?
We do not replace gutters or fascias. If a gutter is broken or sagging, we will tell you so you can call the right trade.
Is gutter cleaning part of the job?
We clear what’s around the joints we work on. Full gutter cleaning is a separate job.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What else we do in Dartmouth Park
What happens if it’s left?
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

How to look after the new joints
Aftercare is simple:
- Clear leaves and moss from the gutters
- Get a dropping gutter looked at quickly
- Glance at the soffit joints now and then
- Deal with a drip before winter
Check the joints after heavy rain. It’s the easiest time to see a leak.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
What affects the quote in Dartmouth Park
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- The old material and how stubborn it is
- How many areas need sealing
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- Photos by email, if that is easy
- The problem you’ve noticed
- Whether it has been sealed before
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job.
What happens on the day
