About our window mastic in Shefford Woodlands
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. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with draughty joints inside around the window and mastic that’s falling out in pieces, across aluminium frames, window sills and composite doors.
In a village or hamlet like Shefford Woodlands, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee.

FAQs for Shefford Woodlands
I let a flat near Hungerford station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can you do window mastic in Shefford Woodlands?
Yes. Our work covers London and the South East, and Shefford Woodlands is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can new window sealant be painted?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Signs you need window mastic in Shefford Woodlands
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
Rented homes near Hungerford station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why it’s worth doing now in Shefford Woodlands
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Shefford Woodlands, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
