Window & door mastic in Cliffe, East Sussex
We cover Cliffe for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
How the visit works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house from start to finish. Parking around Cliffe is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

If you have black, perished sealant on frames and cracked or shrunken mastic around the frame, we can put it right.
In smaller places like Cliffe, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure the drainage slots are not blocked
- Keep timber frames painted
- Keep solvents and bleach off the sealant
- Check the mastic once a year
Most silicone sealants won’t take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that’s a job for a joiner.
Windows and doors in Cliffe
With historic houses such as Anne of Cleves House (about 0.7 miles south-west) nearby, there’s older building stock in the area around Cliffe as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 Priory School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Lewes station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Thomas at Cliffe, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we can’t put right
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Questions from Cliffe
Is Cliffe within the area you cover?
Yes. Cliffe is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do window mastic in Cliffe?
Yes, Cliffe is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long should I leave it?
It depends on the product. Before we leave, we will tell you the cure time.
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.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a smaller place like Cliffe, 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
