Window & door mastic in Maida Vale, Greater London
Problem with your window and door frames in Maida Vale? We remove the old material, prepare the joints and seal them properly.

What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window

Window mastic in Maida Vale
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. We work on timber windows & doors, patio & French doors and composite doors, and common reasons people get in touch are white mastic on grey or black frames and rushed sealant from a window installation.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
All our work is covered by our 12-month guarantee.

Places near Maida Vale
What else we do in Maida Vale
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Do you need window mastic in Maida Vale?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The problems people generally mention when they call are:
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
- Mastic that is falling out in pieces
- Rain getting in at the frame or under the sill
Managing a site like Essendine Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Are they insured?
- When the joint can take water or movement
- How hidden problems are handled
- How the joint is cleaned and prepared
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Your questions about window mastic in Maida Vale
Can you do window mastic in Maida Vale?
Yes, Maida Vale is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is parking an issue for window mastic in Maida Vale?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What affects the quote in Maida Vale
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- The type of property
- Roughly how big the job is
- How we’d reach the joints
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
Why deal with it now?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Maida Vale.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Windows and doors in Maida Vale
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Maida Vale can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Kilburn High Road station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. In a London area like Maida Vale, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
