Window & door mastic in Maidenbower, West Sussex
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Maidenbower. Fully insured, ARBOMaster approved and guaranteed for a year.

- Gaps where the sill meets the wall
- Cracked or shrunken mastic around the frame
Window mastic in Maidenbower
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on patio & French doors, uPVC windows and composite doors, and the jobs we see most are water coming in at the bottom corners of a door and cracked or shrunken mastic around the frame.
In smaller places like Maidenbower, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
All our work comes with our one-year guarantee.

Maidenbower homes and the weather
With historic houses such as Gravetye Manor (about 4.1 miles east) nearby, there’s older building stock in the area around Maidenbower as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Three Bridges station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Brook Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Nicholas' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Questions from Maidenbower
Will you come out to Maidenbower?
Yes, Maidenbower is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should the sealant in an older Maidenbower home be renewed?
If it hasn’t been replaced for some years, it’s generally worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
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 long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
If you manage several properties in or around Maidenbower, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Leave it or put it right?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In a smaller place like Maidenbower, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
- Clear any debris from frame drain holes
- Keep paint off silicone joints
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Maidenbower, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We’ll tell you if that is what we find.
What we can’t put right
Before you book, it’s worth knowing the limits:
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
