Window mastic in Norwood Hill, done properly
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 Norwood Hill. We work on patio & French doors, window sills and uPVC windows, and the jobs we see most are gaps between the frame and the inside reveal and water coming in at the bottom corners of a door.
In a village or hamlet like Norwood Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Norwood Hill homes and 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.
Around Norwood Hill, as everywhere, window mastic is only as good as the preparation behind it. Letting a property close to Horley station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- Whether there’s mould to deal with
- Which sealant suits the joint
- How much there is to do
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Older cottages and farmhouses around Norwood Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. In a small place like Norwood Hill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
