Gutter sealing for homes and businesses in Puddle Dock
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. Typical jobs include internal damp traced to a gutter joint and fascia boards with gaps between them, on gutter joints, roofline trims and soffit joints.
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.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a few hours and we leave things clean and tidy. 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.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Your questions about gutter sealing in Puddle Dock
Can parking be tricky for a visit in Puddle Dock?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Upminster station. Can you help?
Yes, rental work is part of what we do. 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 any work starts.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours, depending on the number of joints and the access. We’ll tell you when we quote.
Is sealant enough for a gutter that has dropped?
No. A sagging gutter pulls its joints apart so it needs refixing before sealing.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Outside joints around Puddle Dock
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 Hare Hall (about 4.1 miles north-west) are a reminder that the area around Puddle Dock 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.
As a London address, Puddle Dock can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Upminster station, leaking gutter joints on a rental are best caught before they stain the walls.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check the gutters during heavy rain
- Have sagging gutters refixed early
- Don’t lean ladders against the gutter itself
- Keep downpipes clear
Keep the gutters clear of leaves and moss so water does not sit on the joints. Standing water strains every seal.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What affects the cost of gutter sealing
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether the work is at height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

What the job involves on each surface
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
Gutter end caps
End caps take the pressure of water running along the gutter. When their seal fails, they drip.
Do you need gutter sealing in Puddle Dock?
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
Keep an eye out for these signs:
- Old gutter sealant that has let go
- Wet patches on the wall under a gutter joint
- Stop ends leaking at the end of a run
- Cracked sealant along roofline trims
If you look after a building such as The James Oglethorpe Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Is VAT in the price?
- How the joint is cleaned and prepared
- Are they insured?
- How the colour is chosen
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Guttering that needs replacing
- Brackets that have snapped or loosened
- Boards that have decayed or split
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
