Window mastic in Bachelor's Bump, done properly

Around Bachelor's Bump 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. We work on aluminium frames, patio & French doors and window sills, and the jobs we see most are water coming in at the bottom corners of a door and untidy mastic left by window fitters.

Homes in small places like Bachelor's Bump often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

There’s a 12-month guarantee on every job.

Landlord and commercial work in Bachelor's Bump

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

Looking after it afterwards

After the cure time, these simple habits help:

  • Ventilate rooms so frames do not stay wet inside
  • Walk round the house once a year and look at the joints
  • Keep paint and stain on wooden frames in good order
  • Don’t aim a pressure washer at the joints

Silicone cannot usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.

Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

What we can’t put right

We’ll always be straight with you, so here’s what new sealant will not do:

  • Broken hinges, locks or handles
  • Condensation trapped between the panes
  • Penetrating damp from a failed cavity tray or render

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Where we work in Bachelor's Bump

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

What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Bachelor's Bump, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on

Advice

Your questions about window mastic in Bachelor's Bump

Is window mastic in a coastal place like Bachelor's Bump any different?

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 you help a landlord with a rental near Three Oaks station?

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.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

What information do you need?

Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.

Can new sealant go over the old?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Can you do upstairs windows?

Usually, yes. We plan safe access before the job, so mention the height and anything in the way.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Bachelor's Bump, along with the rest of our area.

How long does it take to reseal the windows on a house?

A few frames take a few hours. We confirm the timing with your quote.

DIY versus a professional 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, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Signs you need window mastic in Bachelor's Bump

Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.

If you can see any of these, it’s time to have the joints looked at:

  • Water coming in at the bottom corners of a door
  • Cracked internal joints between frame and plaster
  • Mastic that has split away from the wall
  • Gaps left after new windows were fitted

For site and facilities teams at buildings such as The Hastings Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Before booking anyone

  • How much experience the applicator has
  • What guarantee comes with the work
  • Whether you can choose the colour
  • What product goes in the joint

How to choose a mastic man

Bachelor's Bump homes and the weather

Bachelor's Bump 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. 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 Christ Apostolic Church Hastings, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Three Oaks station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
