Window Mastic in Five Oaks
We cover Five Oaks for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- A bead that does not match the frame
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
Do you need window mastic in Five Oaks?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
It’s worth asking for a quote if you see:
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
If you look after a building such as The Weald School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether you can choose the colour
- The length of the guarantee
- Which sealant they’ll use, and why
- How hidden problems are handled
Window mastic in Five Oaks
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have cracked or shrunken mastic around the frame and black, perished sealant on frames, we can put it right.
Homes in small places like Five Oaks often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our 12-month guarantee in Five Oaks and across West Sussex.

Questions from Five Oaks
Do you work for landlords with property near Billingshurst station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Five Oaks?
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.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does the work come with a guarantee?
Yes. Our 12-month guarantee covers every job.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Five Oaks, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Five Oaks can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on

Surface by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
