About our window mastic in Aylesford
Around Aylesford we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, patio & French doors and composite doors, and the jobs we see most are water coming in at the bottom corners of a door and sealant in the wrong colour for the frame.
In a smaller place like Aylesford, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a smaller place like Aylesford, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first

The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. For a job in Aylesford, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Keep children and pets away from the work area

What affects the quote in Aylesford
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The size of the job
- The type of sealant required
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- Any previous sealing or DIY work
- The address or postcode of the job
- Photos by email, if that’s easy
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job and send pictures if you have them.
Aylesford homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Starkey Castle (about 4.5 miles north) are a reminder that the area around Aylesford has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Aylesford station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Aylesford Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Aylesford Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Aylesford is about 3 miles north-west of Maidstone, in Kent.

FAQs for Aylesford
Can you help a landlord with a rental near Aylesford station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Aylesford within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you seal inside as well as outside?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
How to look after the new joints
So the new joints stay in good condition:
- Ventilate rooms so frames do not stay wet inside
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
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. Catching it early keeps the fix to a reseal.
What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
