How we handle window mastic in Bolney
Homes in Bolney have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, aluminium frames and composite doors, and people most often call us about black, perished sealant on frames and damp patches on the reveal after heavy rain.
Mastic can only go onto a dry, clean joint, so window work in Bolney is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Quotes for window mastic in Bolney
Every job gets its own quote. This is what makes a difference:

- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Before you ask for a quote, have a think about:
- The address or postcode of the job
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- The problem you’ve noticed
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.

How to look after the new joints
After the cure time, these simple habits help:
- Ventilate rooms so frames don’t stay wet inside
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
- Keep paint off silicone joints
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
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 it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint

Windows and doors in Bolney
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Ockenden Manor (about 2.5 miles east) nearby, there’s older building stock in the area around Bolney as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Bolney CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Wivelsfield station, renewing tired window mastic between tenants heads off draught and damp complaints.

Surface by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
When to call us in Bolney
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
People normally contact us when they notice one of these:
- A bead that doesn’t match the frame
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
Homes close to St Mary Magdalene's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
Before you book anyone
- Whether they’re fully insured
- Which sealant they’ll use, and why
- Is VAT in the price?
- Whether you can choose the colour
The process
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. Somewhere as small as Bolney, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- 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.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Advice
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Around Bolney, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
