What affects the cost of window mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- Access and height
- Mould in or behind the old joints
- The number of rooms or windows
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. The price is agreed before we begin.
Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- The address or postcode of the job
- Photos by email, if that’s easy
We quote each job on its own. Simply phone 0345 464 0079 or drop us an email and describe the job.
Window mastic in Houghton, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with water coming in at the bottom corners of a door and draughts coming in around windows and doors, we can help, whatever the surface.
In a village or hamlet like Houghton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Houghton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
How to get a quote
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
Related advice
What we’re called out for in Houghton
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us include:
- Mastic that’s falling out in pieces
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
Managing a site like Dorset House School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Who does the work, and how experienced they are
- What insurance they hold
- What the cure time is
- Whether you can choose the colour
How to look after the new joints
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
- Don’t aim a pressure washer at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Houghton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before work begins.
What you get with us
- Tidy, careful work
- One-year guarantee on every job

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on

Houghton: your questions answered
Is Houghton within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Amberley station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
How long does it take to reseal the windows on a house?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Frames and glazing around Houghton
With historic houses such as Bignor Roman Villa (about 2.8 miles north-west) nearby, there’s older building stock in the area around Houghton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near The Parish Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Amberley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
