About our window mastic in Picket Piece
Homes in Picket Piece have every kind of window: 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’re often asked to deal with draughty joints inside around the window and cracked or shrunken mastic around the frame, on timber windows & doors, composite doors and aluminium frames.
Around Picket Piece, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same 12-month guarantee in Picket Piece and across Hampshire.

Different surfaces, different methods
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Paint up to the joint, not over it
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What window mastic looks like in Picket Piece
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How we quote for window mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- The old material and how stubborn it is
- How easy the joints are to reach
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- The address or postcode of the job
- The type of property
- Whether it has been sealed before
- Any access issues, like height or stairs
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.
Common questions in Picket Piece
Is Picket Piece in your area for window mastic?
Yes. We work across London and the South East, and Picket Piece is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Picket Piece?
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.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will you leave 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.
How many windows can you do in a day?
A handful of frames is a short visit. You will get a timescale with the quote.
Common problems we fix in Picket Piece
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.
Most people get in touch when they notice something like this:
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
Schools such as Pilgrims' Cross CofE Aided Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- What happens if the job turns out different
- Whether they’re fully insured
- Whether VAT is included
- Whether the sealant suits the joint
The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a morning for a couple of windows and a door. Parking around Picket Piece is usually 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
