Window mastic in Hatfield Broad Oak
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for gaps where the sill meets the wall and sealant in the wrong colour for the frame, on patio & French doors, timber windows & doors and uPVC windows.
Around Hatfield Broad Oak, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same one-year guarantee.

What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Hatfield Broad Oak needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Common problems we fix in Hatfield Broad Oak
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch when they notice one of these:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Rushed sealant from a window installation
- Black, perished sealant on frames
Letting a property close to Sawbridgeworth station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Windows and doors in Hatfield Broad Oak
Historic houses like Barrington Hall (about 0.7 miles north) are a reminder that the area around Hatfield Broad Oak has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

When it isn’t the sealant

Hatfield Broad Oak: your questions answered
Will you come out to Hatfield Broad Oak?
Yes, Hatfield Broad Oak is covered. 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.
I let a flat near Sawbridgeworth station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can you get sealant to suit coloured frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you do upstairs windows?
Generally, yes. Access is planned before any work starts, so mention the height and anything in the way.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Hatfield Broad Oak and across Essex. We can quote a run of properties together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Aftercare tips
A little care helps the new joints last. We recommend:
- Ventilate rooms so frames do not stay wet inside
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
- Clear any debris from frame drain holes
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
