About our window mastic in Epping
Around Epping we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, aluminium frames and composite doors, and the jobs we see most are whistling draughts around closed windows and a bead that doesn’t match the frame.
Homes around Epping range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Epping: your questions answered
Can you do window mastic in Epping?
Yes. We work across London and the South East, and Epping is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
What guarantee comes with window mastic in Epping?
All our work, in Epping and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we’ll choose accordingly.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Windows and doors in Epping
With historic houses such as Hill Hall (about 2.5 miles south-east) nearby, there’s older building stock in the area around Epping as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Epping Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In an older home around Epping, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes a few hours for a few frames, or a day or more for a whole house. A visit to Epping is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
Advice
Signs you need window mastic in Epping
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
People usually contact us when they notice something like this:
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
For an older house near a landmark such as Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Whether the sealant suits the joint
- Whether VAT is included
- Is the old sealant removed completely?
- How much experience the applicator has
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
