Gutter sealing for homes and businesses in Fitzrovia
We work across Fitzrovia on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we will confirm what access is needed. We work on uPVC fascias, gutter joints and garage door frames, and the jobs we see most are wet patches on the wall under a gutter joint and earlier gutter repairs that have peeled off.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Fitzrovia, tell us how high the joints are and how to reach the back of the building.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

How the job changes by surface
Gutter joints
Most gutter leaks start at a joint between sections. They’re cleaned out, dried and resealed.
Garage door frames
The joint between frame and brickwork moves and weathers. An exterior sealant suits them.
Fitzrovia: your questions answered
Is parking a problem for a job in Fitzrovia?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near London Euston station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is it possible to stop a gutter joint dripping with sealant?
Often, yes. A clean, dry joint resealed with gutter sealant generally stops the drip. If the section is split or warped, it needs replacing.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. A full gutter clean is a separate job.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will sealing fix a sagging gutter?
Not on its own. If the gutter sags, the joints keep opening so it needs refixing before sealing.
How long does the job take?
A typical job takes a few hours, depending on the number of joints and the access, including preparation and clearing up. We’ll confirm how long when we quote.
Landlords, agents and businesses in Fitzrovia
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What gutter sealing looks like in Fitzrovia
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Handel Hendrix House (about 0.8 miles south-west) are a reminder that the area around Fitzrovia has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Whitefield's Tabernacle, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as All Souls CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s.

When to call us in Fitzrovia
End caps get knocked or pushed by water. Once the seal behind them fails, they drip and runs down the wall.
Most people get in touch when they notice one of these:
- Water running down the wall below the gutter
- Damp patches inside below a leaking gutter
- Trim joints where the sealant has failed
- Water dripping where gutter sections meet
Fitzrovia is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- How the colour is chosen
- The length of the guarantee

- Are they insured?
How the visit works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Fitzrovia. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Preparing for the visit

- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

What affects the quote in Fitzrovia
There’s no set price list. What we look at:
- The old material and how stubborn it is
- The product the joint needs
- The size of the job
- How easy the joints are to reach
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- A few photos by email, if you can
- Any access issues, like height or stairs
- The rough size of the job
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Why act early in Fitzrovia
Sealant will not clear a blocked downpipe. We check the cause first and point you to the right trade if needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Fitzrovia, the repair is bigger than a sealant job.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
