Window Mastic in Hothfield
Window and door frames in Hothfield need attention? We remove the old material, prepare the joints and seal them properly.
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t 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 Hothfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- A 12-month guarantee on all work
- 4.9 on Google from 180+ five-star reviews
- Fully insured
- Colour agreed with you before we start

Window mastic for homes and businesses in Hothfield
Around Hothfield we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on aluminium frames, composite doors and uPVC windows, and people most often call us about old mastic that has gone black or come away and gaps left after new windows were fitted.
Somewhere as small as Hothfield, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same 12-month guarantee in Hothfield and across Kent.

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- How many areas need sealing
- The old material and how stubborn it is
- When we can work, for business premises
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If someone has resealed it before
- The address or postcode of the job
If you are in Hothfield and need window mastic, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Hothfield: your questions answered
Is Hothfield in your area for window mastic?
Yes. We work across London and the South East, and Hothfield is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Will you come out to Hothfield?
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.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house for a typical job. In a small place like Hothfield, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we are called out for in Hothfield
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Common reasons people contact us are:
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
If you look after a building such as The Hayesbrook School, larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames do not stay wet inside
- Keep jet washers away from the mastic
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Windows and doors in Hothfield
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Godinton House (about 1 mile south-east) nearby, there’s older building stock in the area around Hothfield as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Charing station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Margaret, the joint between an old wall and a newer frame is normally the first place rain gets in.
