Window Mastic in Hurlingham
Our applicators work in Hurlingham on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
- Leaking joints at the ends of sills
Window mastic in Hurlingham, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with rushed sealant from a window installation and mastic that has split away from the wall, we can put it right, whatever the surface.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
Big or small, it’s backed by our 12-month guarantee in Hurlingham and across Greater London.

Questions from Hurlingham
I let a flat near Imperial Wharf station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Can parking be tricky for a visit in Hurlingham?
Parking in Hurlingham, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can you do the inside joint as well?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What affects the quote in Hurlingham
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Mould in or behind the old joints
- Working hours on commercial sites
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
To make quoting easier, please include:
- The address or postcode of the job
- The rough size of the job
- Access, such as stairs, a lift or height
- The type of property
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Honest limits
In fairness, some problems need a different trade:
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- uPVC windows
- Timber windows & doors
- Window sills
- Patio & French doors
- Composite doors
- Aluminium frames
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. In Hurlingham, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Clear the area around the work

Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. 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.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- White, clear, grey or another colour, product permitting
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
- A sealant colour to suit the surroundings

Hurlingham homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around St Dionis, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Imperial Wharf station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Sulivan Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
