Yes, smaller places are covered as well as towns. We work across 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 Hatfield station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Window mastic in Smallford
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just call 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached for window mastic in Smallford. We work on aluminium frames, uPVC windows and window sills, and common reasons people get in touch are untidy mastic left by window fitters and whistling draughts around closed windows.
In a village or hamlet like Smallford, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in Smallford
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
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 that we can handle for you.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Smallford, 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.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

- Draughts through the window seals rather than the frame
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Common problems we fix in Smallford
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
People usually contact us after spotting something like this:
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
In the older streets around Church of St Mark, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- What happens if the job turns out different
- How long the guarantee is
- Is VAT in the price?
- Whether you can choose the colour
Frames and glazing around Smallford
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. With historic houses such as Hatfield House (about 2.7 miles east) nearby, there’s older building stock in the area around Smallford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Hatfield station, renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Nicholas Breakspear Catholic School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Where a wall is exposed, as many are in small places like Smallford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
