Gutter sealing in Rush Green, done properly
Gutter and fascia replacement is not our trade, and nor is roofing. Sealant fixes joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on uPVC fascias, roofline trims and gutter joints, and the jobs we see most are fascia boards with gaps between them and leaking gutter joints and stop ends.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
All our work comes with our 12-month guarantee, wherever you are in Greater London.

How we quote for gutter sealing
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The rough size of the job
- The type of property
- Any previous sealing or DIY work
- How we’d reach the joints
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes an hour or two for a few joints, longer for a full run for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- The joints are checked once sealed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Your questions about gutter sealing in Rush Green
Can parking be tricky for a visit in Rush Green?
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 Romford station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Will you clear out my gutters?
Only around the joints we seal, so the sealant can bond. A full gutter clean is a separate job.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Rush Green, along with the rest of our area.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you do several jobs on one visit?
Yes. Just list everything you need.
What gutter sealing looks like in Rush Green
Historic houses like Hare Hall (about 2.1 miles north-east) are a reminder that the area around Rush Green has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Romford station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Schools such as Rush Green Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
uPVC fascias
Gaps in fascias spoil the roofline. A neat bead closes them up.
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Get leaks sealed before the wet months
- Watch the wall under the gutters for staining
- Get a dropping gutter looked at quickly
- Do not lean ladders against the gutter itself
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
Common problems we fix in Rush Green
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
Look out for any of the following:
- Internal damp traced to a gutter joint
- Fascia boards with gaps between them
- Stop ends leaking at the end of a run
- Failed sealant on a garage door frame
Rush Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before booking
- Whether all the old sealant comes out first
- How hidden problems are handled
- Are they insured?
- How long the guarantee is
What happens if it’s left?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Proper preparation is the difference. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
