Tufnell Park Gutter Sealing
Problem with your gutter and fascia joints in Tufnell Park? We remove the old material, prepare the joints and seal them properly.
- Internal damp traced to a gutter joint
- Stop ends leaking at the end of a run
- Old sealant on roofline trims that has split
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look for streaks or damp on the wall below gutters
- Get a dropping gutter looked at quickly
- Clean out the gutters once or twice a year
- Sort out a dripping joint early
Keep downpipes clear, so water can get away. A blocked pipe backs water up to the joints.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches.
Gutter sealing in Tufnell Park
Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first, then dry the joint before sealing. We work on gutter joints, soffit joints and gutter end caps, and common reasons people get in touch are fascia boards with gaps between them and earlier gutter repairs that have peeled off.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. For a flat in Tufnell Park, check the lease for who looks after the outside.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What the job involves on each surface
Roofline trims
Sealing roofline trims is joint work only. A roofer deals with the roof itself.
Soffit joints
Open soffit joints let draughts in. We close them with a suitable sealant.

What happens if it’s left?
You do not need to replace a garage door because rain gets in round the frame. Sealing the frame usually stops it, if the frame itself is sound. In a flat in Tufnell Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes an hour or two for a few joints, longer for a full run. For a job in Tufnell Park, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Advice
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, 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.
Questions from Tufnell Park
Can parking be tricky for a visit in Tufnell Park?
Parking in Tufnell Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Upper Holloway station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will sealant fix a dripping gutter joint?
Often, yes. Cleaning, drying and resealing the joint usually works. If the section is split or warped, it needs replacing.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can I add another job to the visit?
Yes. Just list everything you need.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How do I get a quote for gutter sealing in Tufnell Park?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Water backing up from a blocked pipe
- Leaks from the roof rather than a joint
- A gutter length that has split
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Outside joints around Tufnell Park
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Witanhurst (about 1.2 miles north-west) are a reminder that the area around Tufnell Park has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Eleanor Palmer Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Tufnell Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Rented homes near Upper Holloway station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
