Gutter sealing in Hornchurch Marshes
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. Common call-outs are for dripping gutter ends and garage door frames letting rain in, across gutter joints, soffit joints and garage door frames.
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 Hornchurch Marshes, it’s worth checking who is responsible for the outside before booking.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Hornchurch Marshes: your questions answered
Is parking a problem for a job in Hornchurch Marshes?
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.
Is Hornchurch Marshes in your area for gutter sealing?
Yes, Hornchurch Marshes is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you replace gutters or fascias?
No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Is gutter cleaning part of the job?
The joints we seal are cleaned out and any debris nearby is cleared. Cleaning the whole run is a different job.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you guarantee gutter sealing?
There’s a 12-month guarantee on every job, gutter and fascia work included.
Honest limits
A few problems are outside what sealant work can do:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Fascias that need replacing
- Water backing up from a blocked pipe
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Landlords, agents and businesses in Hornchurch Marshes
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
What happens if it’s left?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job before the damage spreads. 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.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Aftercare tips
To keep the joints looking good and working properly:
- Deal with a drip before winter
- Clear leaves and moss from the gutters
- Get a dropping gutter looked at quickly
- Check that water runs out of the downpipes
Give the sealant the cure time we tell you before poking or cleaning near it.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
