Window mastic in Iping
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for mastic that’s falling out in pieces and gaps where the sill meets the wall, across aluminium frames, window sills and timber windows & doors.
Homes in small places like Iping often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

When to call us in Iping
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
People generally contact us after spotting one of these:
- White mastic on grey or black frames
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
If you look after a building such as Stedham Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone
- Who turns up on the day
- How long to leave it before use
- Whether they seal over old material or remove it
- Are they insured?
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of frames, longer for a whole house. In a small place like Iping, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Before we arrive
- Tell us about any water getting in
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Advice
Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
Iping: your questions answered
Do you cover Iping for window mastic?
Yes, Iping is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Liphook station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Iping.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
How we quote for window mastic
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- The type of sealant required
- How easy the joints are to reach
- The amount of work
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- The type of property
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or email us with the details.

Window mastic in Iping: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Cowdray House (about 2.5 miles east) nearby, there’s older building stock in the area around Iping as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Liphook station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Local landmarks in Iping
Typical jobs here are in homes near Midhurst Rother College. The nearest railway station is Liphook station, about 5 miles north of the centre. A little further out are Midhurst Museum (2.2 miles south-east) and Midhurst Community Hospital (2.2 miles east). Not far away are Iping and Stedham Commons and Wheeler's Down.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Older cottages and farmhouses around Iping can have timber floors and frames, and water through a failed joint can rot timber 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 make a difference, and we will explain the quote if you ask.
