Window mastic for homes and businesses in Radfall
From a single sill to a whole house of windows, the work is priced before anything is done. Just call 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached for window mastic in Radfall. Common call-outs are for rain getting in at the frame or under the sill and gaps between the frame and the inside reveal, across composite doors, patio & French doors and window sills.
Homes in small places like Radfall often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Window mastic in Radfall: local notes
Radfall is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts 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 Chestfield & Swalecliffe station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Radfall, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Tell us about any water getting in

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
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 check before we reseal.
Common questions in Radfall
I let a flat near Chestfield & Swalecliffe station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is window mastic in a coastal place like Radfall any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
How many windows can you do in a day?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Do you cover Radfall?
We do. Radfall is part of the area we cover.
Are you insured?
Yes. We’re fully insured.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Do you need window mastic in Radfall?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
These are the problems we’re asked about most:
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
For site and facilities teams at buildings such as The Whitstable School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Is the old sealant removed completely?
- What guarantee comes with the work
- Whether you can choose the colour
- Are they insured?
Keeping the joints in good condition
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
- Wash the frames with mild soapy water
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.
Why act early in Radfall
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. In a small place like Radfall, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: 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 will go through it with you.
What you get with us
