Manston: your questions answered

Is Manston within the area you cover?

Yes. Manston is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Does the coastal weather in Manston affect outside sealant?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Can landlords and businesses book you?

Yes, regularly. Several properties can go on one quote.

Can I paint over the new sealant?

That depends on the product. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before we start.

Do you have insurance?

Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.

Do you seal inside as well as outside?

Yes. Indoors, we seal between the frame and the plaster or reveal.

Will it make a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Can tenants book the work?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Window mastic in Manston, done properly

Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have gaps between the frame and the inside reveal and white mastic on grey or black frames, we can put it right, on timber windows & doors, patio & French doors and aluminium frames alike.

Mastic can only go onto a dry, clean joint, so window work in Manston is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

A one-year guarantee comes as standard, so you are covered after we’ve gone.

Different surfaces, different methods

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.

Window sills

The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Look round the frames every year or so
  • Ventilate rooms so frames do not stay wet inside
  • Keep jet washers away from the mastic
  • Clean frames with a soft cloth and soapy water

Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.

Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

When something else is needed

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window
  • Worn gaskets, brush seals or a door that has dropped

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Joints and surfaces we work on

  • Composite doors
  • Aluminium frames
  • Patio & French doors
  • Window sills
  • uPVC windows
  • Timber windows & doors

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Why act early in Manston

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In a small place like Manston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Landlords, agents and businesses in Manston

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What happens on the day

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a morning for a couple of windows and a door for a typical job. Somewhere as small as Manston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Let us know about stairs, lifts or work at height
  • Try not to wet indoor joints just before the visit

Advice

Window mastic in Manston: local notes

Manston is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Managing a site like Newington Community Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Thanet Parkway station? Then renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around St. Catherine's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Manston is about 2 miles west of Ramsgate, in Kent. Whether you are in the middle of Manston or further out, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels.
