Window & door mastic in Cogges, Oxfordshire
Our applicators work in Cogges on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
- Leaking joints at the ends of sills
How we handle window mastic in Cogges
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include cracked sealant at the sill ends and water coming in at the bottom corners of a door, across composite doors, aluminium frames and timber windows & doors.
Homes around Cogges range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Why it’s worth doing now in Cogges
Resealing frames is a short job: it 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. Homes in smaller places like Cogges can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Do you need window mastic in Cogges?
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.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
For site and facilities teams at buildings such as The Blake Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What window mastic looks like in Cogges
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. With historic houses such as Minster Lovell Hall (about 2.5 miles north-west) nearby, there’s older building stock in the area around Cogges 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 is traditional sand mastic.
For landlords with property near Finstock station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Surface by surface
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take most of a day for a typical house, less for a few frames. For a job in Cogges, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Cogges questions
Is Cogges within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Cogges for window mastic?
Yes, Cogges is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
