DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.

Common call-outs are for draughts coming in around windows and doors and rushed sealant from a window installation, on uPVC windows, window sills and timber windows & doors.

Why it’s worth doing now in Mayes Green
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Mayes Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Mayes Green homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Ockley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
How we quote for window mastic
We don’t publish a price list. What we look at:
- The product the joint needs
- Whether there’s mould to deal with
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- If someone has resealed it before
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Landlord and commercial work in Mayes Green
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Mayes Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
Ask for a quote
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.

Mayes Green questions
Is Mayes Green within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Ockley station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
