- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
Different surfaces, different methods
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
How we handle window mastic in Hockley
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We’re often asked to deal with sealant in the wrong colour for the frame and draughts coming in around windows and doors, across patio & French doors, composite doors and uPVC windows.
In a smaller place like Hockley, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we are called out for in Hockley
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
It’s worth asking for a quote if you see:
- Black, perished sealant on frames
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
Schools such as Greensward Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
- Who does the work, and how experienced they are
- How long the guarantee is
What window mastic looks like in Hockley
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hockley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Emmanuel Church Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take most of a day for a typical house, less for a few frames. For a job in Hockley, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Mention if the joints have been sealed before

Looking after it afterwards
To keep the joints looking good and working properly:
- Do not paint over the silicone
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
- Walk round the house once a year and look at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Are you ARBOMaster approved?

Can I paint over the new sealant?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
