Windows and doors in Angell Town
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as St John's Angell Town Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Sand mastic in Angell Town
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on brick reveals, timber door frames and tenement windows, and common reasons people get in touch are silicone on a period window that looks wrong and weathered mastic on the most exposed windows.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Angell Town as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

Surface by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
When something else is needed
We will not take on work that won’t last, so these are the limits:
- Crumbling stone or brickwork round the window
- Decayed frames that need repair
- Decisions on consent for listed homes
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from a few hours to a full day, depending on how many windows. For a job in Angell Town, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Advice
Your questions about sand mastic in Angell Town
Is parking a problem for a job in Angell Town?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you do sand mastic in Angell Town?
Yes. Our work covers London and the South East, and Angell Town is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later, and we will tell you what to expect.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Landlord and commercial work in Angell Town
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Looking after it afterwards
So the new joints stay in good condition:
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
- Look over the window mastic once a year
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
