About our window mastic in Birdbrook
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. Where the air is getting in through the window itself, we’ll say so. We work on uPVC windows, window sills and patio & French doors, and people most often call us about gaps between the frame and the inside reveal and draughts coming in around windows and doors.
Homes in small places like Birdbrook often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Questions from Birdbrook
What guarantee comes with window mastic in Birdbrook?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you do window mastic in Birdbrook?
Yes. We work across London and the South East, and Birdbrook is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
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.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
What the job involves on each surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Honest limits
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- A frame that has rotted at the joint
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.

What we’re called out for in Birdbrook
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- A bead that does not match the frame
Homes close to Parish Church of St Augustine include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How the colour is chosen
- Whether they seal over old material or remove it
- How hidden problems are handled
- How long to leave it before use
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
For anyone letting property in or around Birdbrook, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep drainage slots and sill grooves clear
- Ventilate rooms so frames don’t stay wet inside
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What affects the cost of window mastic
There’s no set price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Access and height
- Whether there’s mould to deal with
- The product the joint needs
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- The type of property
- How we’d reach the joints
Every job is quoted individually. Just call 0345 464 0079 or drop us an email with the details and send photos if you have them.
How it works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job generally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Birdbrook, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
