Leave it or put it right?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In a smaller place like Fratton, 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.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Arbo and Everbuild products
- Every job guaranteed for a year
- Any old sealant cut out fully, not covered over
- We agree the colour with you first

About our window mastic in Fratton
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. Common call-outs are for leaking joints at the ends of sills and gaps left after new windows were fitted, on composite doors, patio & French doors and window sills.
In smaller places like Fratton, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

What affects the quote in Fratton
The quote reflects the job in front of us. We take into account:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- When we can work, for business premises
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

There’s no need for technical detail. Just tell us:

- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work

How it works
We keep the work tidy and contained to the area we are working on. The job generally takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Fratton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Clear items away from the joints we are working on
- Mention any tricky access
- Keep pets and children clear of the area while we work

Advice
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:
- Rotten timber, which needs a joiner first
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Windows and doors in Fratton
Fratton 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Fratton station, renewing tired window mastic between tenants heads off draught and damp complaints.

What we’re called out for in Fratton
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Common reasons people contact us include:
- Water coming in at the bottom corners of a door
- Mastic that’s falling out in pieces
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
For site and facilities teams at buildings such as Penhale Infant School & Nursery, its window and door frames need their mastic kept sound, just like a home’s.

Fratton questions
Will you come out to Fratton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Fratton station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
What information do you need?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Are you insured?
Yes. Full insurance covers our work.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
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.
How long before the joint can be used?
It depends on the product. Before we leave, we’ll tell you the cure time.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Keeping the joints in good condition
Looking after new joints is easy:
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
- Do not paint over the silicone
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: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
