Window mastic for homes and businesses in Ryarsh
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, call 0345 464 0079 or email us with the number of frames and any access details. If you have white mastic on grey or black frames and gaps between the frame and the inside reveal, we can put it right, on composite doors, timber windows & doors and uPVC windows alike.
Mastic can only go onto a dry, clean joint, so window work in Ryarsh is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Ryarsh homes and the weather
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. Historic houses like Starkey Castle (about 4.6 miles north-east) are a reminder that the area around Ryarsh has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Martin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near West Malling station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
Silicone can’t generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Common problems we fix in Ryarsh
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
People usually contact us after spotting something like this:
- Old mastic that has gone black or come away
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
Managing a site like Ryarsh Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Ryarsh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Experience in homes, commercial sites and hotels
- We agree the colour with you first
- Anti-fungal sanitary silicone in wet areas
- We never seal over old sealant

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Ryarsh, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
