Window mastic in Hook Norton, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. We work on patio & French doors, aluminium frames and timber windows & doors, and people most often call us about a bead that doesn’t match the frame and cold air getting in at the frame edge.
Homes around Hook Norton range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
All of our work is guaranteed for twelve months.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. A visit to Hook Norton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
A little care helps the new joints last. We recommend:
- Make sure the drainage slots are not blocked
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames don’t stay wet inside
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
When to call us in Hook Norton
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
Keep an eye out for any of the following:
- Gaps left after new windows were fitted
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
Managing a site like Hook Norton Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- When we can work, for business premises
- How many areas need sealing
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote
To make quoting easier, please include:
- Any previous sealing or DIY work
- Whether it’s a home or a business
- The address or postcode of the job
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Hook Norton: your questions answered
Is there a guarantee on window mastic in Hook Norton?
All our work, in Hook Norton and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do window mastic in Hook Norton?
Yes. Our work covers London and the South East, and Hook Norton is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
What window mastic looks like in Hook Norton
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. With historic houses such as Broughton Castle (about 4.8 miles north-east) nearby, there’s older building stock in the area around Hook Norton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
