Hockley Sand Mastic
Professional sand mastic in and around Hockley, with every bit of old sealant taken out first and a one-year guarantee.
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Homes in smaller places like Hockley can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Sand mastic for homes and businesses in Hockley
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, brick reveals and tenement windows, and common reasons people get in touch are crumbling sand mastic round a window and wind and rain getting in round a sash window.
In smaller places like Hockley, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

FAQs for Hockley
Do you cover smaller places like Hockley?
Yes. Hockley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Hockley station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
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’ll tell you what we’re using.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Do you have insurance?
Yes, we’re fully insured for every job we do.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we will ask.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Hockley homes and the weather
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.
Homes close to Emmanuel Church Hall include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. 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 else we do in Hockley
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. Parking around Hockley is generally 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 start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Signs you need sand mastic in Hockley
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Signs it’s time to call us include:
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
Letting a property close to Hockley station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

- What guarantee comes with the work

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
For landlords and businesses
Landlords and letting agents in Hockley can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What affects the quote in Hockley
We don’t publish a price list, because jobs vary so much. What we look at:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number of rooms or windows
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
