Do you need window mastic in Wendlebury?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us are:
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Rented homes near Bicester Village station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- How long the guarantee is
- How much experience the applicator has
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- A frame that has rotted at the joint
- A sash or casement that won’t close properly
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Window sills
- Timber windows & doors
- Composite doors
- Patio & French doors
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Wendlebury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.
