Window & door mastic in Marden, Kent
Specialist window mastic for Marden: careful preparation, the right product and tidy work. Call for a quick quote.
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
How to look after the new joints
After the cure time, these simple habits help:
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
- Keep timber frames painted
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Window mastic in Marden, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have cold air getting in at the frame edge and a bead that doesn’t match the frame, we can put it right, on patio & French doors, uPVC windows and timber windows & doors alike.
In smaller places like Marden, 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.
You get a 12-month guarantee, the same in Marden as everywhere else we work.

Signs you need window mastic in Marden
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.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
Rented homes near Marden station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Broken hinges, locks or handles
- Damp problems in the wall away from the window
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Marden 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.
In the older streets around St Michael and All Angels Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Marden Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
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.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Questions from Marden
I let a flat near Marden station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover Marden for window mastic?
Yes. We work across London and the South East, and Marden is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
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 so we can plan the job.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What we do, step by step
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Marden, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
