About our window mastic in Heckfield
Homes in Heckfield have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on uPVC windows, patio & French doors and composite doors, and people most often call us about draughty joints inside around the window and sealant in the wrong colour for the frame.
Homes in small places like Heckfield 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.
Every job is covered by a one-year guarantee, wherever you are in Hampshire.

What window mastic looks like in Heckfield
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stratfield Saye House (about 1.7 miles west) are a reminder that the area around Heckfield 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.
Homes close to Church of St Michael include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Daneshill School, its window and door frames need their mastic kept sound, just like a home’s.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint

Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Heckfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Heckfield questions
Do you work for landlords with property near Mortimer station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover Heckfield for window mastic?
Yes. Our work covers London and the South East, and Heckfield is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you do upstairs windows?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
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 new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Surface by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Landlords, agents and businesses in Heckfield
If you manage several properties in or around Heckfield, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. For a village or hamlet like Heckfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

What we’re called out for in Heckfield
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Keep an eye out for any of the following:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
If you let a flat or house near Mortimer station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
