About our window mastic in Tattenhoe
Homes in Tattenhoe have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on composite doors, aluminium frames and uPVC windows, and common reasons people get in touch are a bead that doesn’t match the frame and old mastic that has gone black or come away.
Homes around Tattenhoe 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.
Big or small, you get the same one-year guarantee in Tattenhoe and across Milton Keynes.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Surface by surface
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
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.
How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes most of a day for a typical house, less for a few frames. For a job in Tattenhoe, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Advice
Your questions about window mastic in Tattenhoe
Can you help a landlord with a rental near Bletchley station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Can you do window mastic in Tattenhoe?
Yes, Tattenhoe is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.

When to call us in Tattenhoe
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Look out for these signs:
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
For landlords with property near Bletchley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ventilate rooms so frames do not stay wet inside
- Make sure the drainage slots aren’t blocked
- Don’t use solvent cleaners on the joint
- Wash the frames with mild soapy water
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Windows and doors in Tattenhoe
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 Bletchley Park (about 2.1 miles east) are a reminder that the area around Tattenhoe has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as St Giles's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Giles Brook Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
