What the job involves on each surface
Gutter joints
Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
Garage door frames
The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
How we handle gutter sealing in Nine Elms
Sealant only bonds to a clean, dry joint. That’s why we take out the old sealant and dirt first, then dry the joint before sealing. We are often asked to deal with water dripping where gutter sections meet and old gutter sealant that has let go, across garage door frames, roofline trims and uPVC fascias.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common questions in Nine Elms
Is parking an issue for gutter sealing in Nine Elms?
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.
Can you do gutter sealing in Nine Elms?
Yes, Nine Elms is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
How long does the job take?
That depends on the amount of work, but as a guide it takes anything from an hour or two to a few hours. We’ll tell you when we quote.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Do you take out the old sealant first?

What guarantee comes with the job?
You get our 12-month guarantee on every job.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What gutter sealing looks like in Nine Elms
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. Historic houses like Carlyle's House (about 1.1 miles west) are a reminder that the area around Nine Elms 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.
As a London address, Nine Elms can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes an hour or two for a few joints, longer for a full run. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Nine Elms. It helps if you can point us to a visitor permit or a bay close to the door.
- First we trace the drip and check the gutter is not damaged.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

How we quote for gutter sealing
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- The number of rooms or windows
- How much there is to do
- How easy the joints are to reach
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- Whether it’s a home or a business
- Roughly how big the job is
- Photos by email, if that’s easy
Need a quote? Please ring 0345 464 0079 or drop us an email with a few details. We will explain what we’d do and send you a clear quote before any work starts.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Make sure downpipes aren’t blocked
- Keep the gutters clear of debris
- Keep ladders off the guttering
- Look along the fascias for open joints
Give the sealant the cure time we tell you before poking or cleaning near it.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
Why act early in Nine Elms
Leaving a leaking end cap can send water down the wall all winter. 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 tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
