Outside joints around Crouch End
With historic houses such as Witanhurst (about 1.5 miles south-west) nearby, there’s older building stock in the area around Crouch End as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
As a London address, Crouch End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Schools such as Rokesly Infant & Nursery School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Gutter sealing in Crouch End
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. If you are dealing with water running down the wall below the gutter and dripping gutter ends, we can put it right, whatever the surface.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Crouch End, it’s worth checking who is responsible for the outside before booking.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take an hour or two for a few joints, longer for a full run. In Crouch End, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
Before we arrive
- Keep pets and children clear of the area while we work

Advice
How to look after the new joints
Looking after new joints is easy:
- Check the gutters during heavy rain
- Get a dropping gutter looked at quickly
- Keep the gutters clear of debris
- Look along the fascias for open joints
Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

If you manage several properties in or around Crouch End, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
What happens if it’s left?
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. 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.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Crouch End: your questions answered
Can you do gutter sealing in Crouch End?
Yes. Our work covers London and the South East, and Crouch End is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can parking be tricky for a visit in Crouch End?
Parking in Crouch End, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Are you fully insured?
Yes. We’re fully insured.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Do you install new fascias or gutters?
We don’t replace gutters or fascias. If a gutter is broken or sagging, we will tell you.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Common problems we fix in Crouch End
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
These are the problems we are asked about most:
- Stop ends leaking at the end of a run
- Failed sealant on a garage door frame
- Damp patches inside below a leaking gutter
- Fascia boards with gaps between them
If you let a flat or house near Crouch Hill station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
What your quote should include
- Is VAT in the price?
- What insurance they hold
- When the joint can take water or movement

Quotes for gutter sealing in Crouch End
The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
