DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
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.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

Windows and doors in Littleton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Harestock Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Winchester station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Church of St Catherine 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 we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. Somewhere as small as Littleton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Related advice
Why act early in Littleton
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Littleton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why Littleton customers choose us

What sealant work cannot fix
It helps to know what we cannot do too:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal

Littleton questions
Can you do window mastic in Littleton?
Yes, Littleton is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is Littleton within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- Whether there’s mould to deal with
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us.
