Bewbush Window Mastic
Our applicators work in Bewbush on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
Window mastic in Bewbush, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for hard, cracked sealant around windows and gaps between the frame and the inside reveal, across window sills, uPVC windows and patio & French doors.
In a smaller place like Bewbush, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Frames and glazing around Bewbush
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. Crawley, which Bewbush is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. That mastic ages as well, and sills and frame heads are where leaks start.
If you look after a building such as The Bewbush Academy, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Ifield station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around St Alban's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Bewbush is about 1 mile west of Crawley, in West Sussex. Jobs in Bewbush get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. 371 places in West Sussex are on our list.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Composite doors
- Timber windows & doors
- Window sills
- Patio & French doors
- Aluminium frames
- uPVC windows
What affects the quote in Bewbush
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- Any working-time requirements on site
- Access and height
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- The problem you’ve noticed
- The address or postcode of the job
- The type of property
We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details.
What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. Parking around Bewbush is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Advice
Aftercare tips
Good habits help new joints last longer. Our tips:
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
- Don’t use solvent cleaners on the joint
- Wipe condensation off the frames
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

FAQs for Bewbush
Is Bewbush within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Ifield station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
