Window mastic for homes and businesses in Mockbeggar
The mastic around a window or door seals the gap between the frame and the wall. 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. We work on timber windows & doors, aluminium frames and uPVC windows, and people most often call us about damp patches on the reveal after heavy rain and cracked sealant at the sill ends.
Homes in small places like Mockbeggar 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Window mastic in Mockbeggar: local notes
Mockbeggar is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Temple Manor (about 2.3 miles south) nearby, there’s older building stock in the area around Mockbeggar as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Temple Manor, about 2.3 miles south, is one of the historic houses in the wider area around Mockbeggar. Schools such as Cliffe Woods Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Mockbeggar questions
Does living near the coast affect window mastic in Mockbeggar?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
I let a flat near Higham station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new window sealant be painted?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you do upstairs windows?
Yes, in most cases. Access is planned before work begins, so mention the height and anything in the way.
When to call us in Mockbeggar
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us are:
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
For landlords with property near Higham station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- What the quote includes, VAT included or not
- Whether they’re fully insured
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
What happens if it’s left?
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Mockbeggar can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.
