How we handle window mastic in Botley
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we will say so. Common call-outs are for water coming in at the bottom corners of a door and old mastic that has gone black or come away, across aluminium frames, patio & French doors and uPVC windows.
In a smaller place like Botley, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Big or small, it’s backed by our one-year guarantee.

What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. The work normally takes a morning for a couple of windows and a door. Parking around Botley is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

What affects the quote in Botley
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- When we can work, for business premises
- Access and height
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- The address or postcode of the job
- Any access issues, like height or stairs
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a smaller place like Botley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

Signs you need window mastic in Botley
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Look out for any of the following:
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
Schools such as Botley Church of England Controlled Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- What product goes in the joint
- When the joint can take water or movement
- How the colour is chosen
- Is the old sealant removed completely?

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Timber windows & doors
- Window sills
- Composite doors
- Patio & French doors

What window mastic looks like in Botley
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. Historic houses like South Stoneham House (about 4.6 miles west) are a reminder that the area around Botley has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Botley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.
