Window mastic in Chipping Ongar
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on timber windows & doors, aluminium frames and window sills, and common reasons people get in touch are cracked internal joints between frame and plaster and mastic that has split away from the wall.
Houses in smaller places like Chipping Ongar can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. Parking around Chipping Ongar is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Frames and glazing around Chipping Ongar
Historic houses like Hill Hall (about 4.4 miles south-west) are a reminder that the area around Chipping Ongar 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’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as United Reformed Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Chipping Ongar Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
Chipping Ongar is about 6 miles north-west of Brentwood, in Essex.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
- Wipe condensation off the frames
- Wash the frames with mild soapy water
Most silicone sealants will not take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
How we quote for window mastic
There’s no set price list. The quote depends on:
- Working hours on commercial sites
- Any mould that needs treating
- How much there is to do
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
What we need to know
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- Where the property is
- A few photos by email, if you can
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Landlord and commercial work in Chipping Ongar
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
