Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Window mastic in Whitemans Green, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on uPVC windows, patio & French doors and timber windows & doors, and the jobs we see most are gaps between the frame and the inside reveal and cold air getting in at the frame edge.
Mastic can only go onto a dry, clean joint, so window work in Whitemans Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

When to call us in Whitemans Green
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
If you look after a building such as Holy Trinity Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Whitemans Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

How to look after the new joints
Looking after new joints is easy:
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
- Ventilate rooms so frames don’t stay wet inside
- Do not use solvent cleaners on the joint
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Leaks generally 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.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Whitemans Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- 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
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Frames and glazing around Whitemans Green
Historic houses like Ockenden Manor (about 0.6 miles south) are a reminder that the area around Whitemans Green 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. 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.
If you let a flat or house near Haywards Heath station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Surfaces we seal
- Patio & French doors
- Composite doors
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Window sills
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
