Window mastic in Kirtlington
Every window and door frame has a gap around it, and mastic is what closes it. 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 composite doors, uPVC windows and window sills, and people most often call us about old mastic that has gone black or come away and whistling draughts around closed windows.
Homes in small places like Kirtlington often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
Honest limits
In fairness, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Faulty window hardware
- A failed sealed unit that has misted up
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Your questions about window mastic in Kirtlington
Do you work for landlords with property near Tackley station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is Kirtlington 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.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Can you reach windows above the ground floor?
Yes, in most cases. Access is planned before we start, so mention the height and anything in the way.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What happens on the day
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 a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Kirtlington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before

Surface by surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Frames and glazing around Kirtlington
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. Historic houses like Blenheim Palace (about 4.3 miles south-west) are a reminder that the area around Kirtlington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Tackley station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Kirtlington Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in Kirtlington
Jobs vary more than people expect. The main factors:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The number and length of the joints
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Where the property is
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep timber frames painted
- Wash the frames with mild soapy water
- Check the mastic once a year
- Keep jet washers away from the mastic
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
