How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere like Twitton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit

Advice
Window mastic in Twitton
Around Twitton we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have draughty joints inside around the window and cracked or shrunken mastic around the frame, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Twitton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Why it’s worth doing now in Twitton
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a small place like Twitton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What window mastic looks like in Twitton
With historic houses such as Lullingstone Castle (about 3.3 miles north) nearby, there’s older building stock in the area around Twitton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Otford Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Dunton Green station, renewing tired window mastic between tenants heads off draught and damp complaints.

When it is not the sealant
We will not take on work that will not last, so here’s what sealant cannot put right:
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
- A failed sealed unit that has misted up
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Aluminium frames
- uPVC windows
- Composite doors
- Patio & French doors
- Window sills
- Timber windows & doors
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Twitton questions
Can you help a landlord with a rental near Dunton Green station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover Twitton for window mastic?
Yes, Twitton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
What we’re called out for in Twitton
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Keep an eye out for any of the following:
- Gaps left after new windows were fitted
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Cracked or shrunken mastic around the frame
In the older streets around Twitton Mission Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- How long the guarantee is
- How much experience the applicator has
- Whether they seal over old material or remove it
- What insurance they hold
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
Most silicone sealants won’t take paint, so if you are 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. Resealing closes it.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
