About our window mastic in Oakthorpe Park
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include white mastic on grey or black frames and damp patches on the reveal after heavy rain, across aluminium frames, window sills and timber windows & doors.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
We stand behind the work with a one-year guarantee.

Why it’s worth doing now in Oakthorpe Park
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a flat in Oakthorpe Park, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Oakthorpe Park
- Quality sealants from Arbo and Everbuild
- A 12-month guarantee on all work
- Colour picked to suit the job
- 20+ years of sealant experience

What else we do in Oakthorpe Park
When to call us in Oakthorpe Park
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Signs it’s time to call us include:
- Hard, cracked sealant around windows
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
For landlords with property near Palmers Green station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking
- Who does the work, and how experienced they are
- What guarantee comes with the work
- Whether they’re fully insured
- Whether they seal over old material or remove it
Oakthorpe Park: your questions answered
I let a flat near Palmers Green station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover Oakthorpe Park for window mastic?
Yes, Oakthorpe Park is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How we quote for window mastic
We don’t publish a price list. The quote depends on:
- When we can work, for business premises
- Mould in or behind the old joints
- Which sealant suits the joint
- Whether the work is at height
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- A few photos by email, if you can
- Whether it has been sealed before

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins.

- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.

Oakthorpe Park homes and the weather
Historic houses like Bruce Castle (about 1.7 miles south-east) are a reminder that the area around Oakthorpe Park has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
Managing a site like St Anne's Catholic High School for Girls? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Michael-at-Bowes, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
