Window & door mastic in Bow, Oxfordshire
Mastic around window and door frames, sills and patio doors for Bow, backed by a 12-month guarantee. Call for a quick quote.
- Rain getting in at the frame or under the sill
- Leaking joints at the ends of sills
- Draughty joints inside around the window
Why deal with it now?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Bow, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Window mastic for homes and businesses in Bow
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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on patio & French doors, uPVC windows and composite doors, and the jobs we see most are a bead that doesn’t match the frame and draughts coming in around windows and doors.
Around Bow, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, whatever its size.

Windows and doors in Bow
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Longworth House (about 4.3 miles north-east) are a reminder that the area around Bow has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Stanford in the Vale Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in Bow
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- How much there is to do
- Working hours on commercial sites
- Which sealant suits the joint
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

- The rough size of the job

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
The process
The work is kept neat and contained to the area we are working on. The job usually takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. For a village or hamlet like Bow, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Do you need window mastic in Bow?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
The most common problems we see are:
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
In the older streets around Church of St Denys, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How much experience the applicator has
- What happens if the job turns out different
- What insurance they hold
- What the cure time is
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
