Bedgrove Sand Mastic
Window and door surrounds in Bedgrove need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
How we handle sand mastic in Bedgrove
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on brick reveals, tenement windows and timber door frames, and the jobs we see most are gaps round a timber door in stone or brick and silicone on a period window that looks wrong.
Many houses in smaller places like Bedgrove have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same one-year guarantee.

Your questions about sand mastic in Bedgrove
Do you cover smaller places like Bedgrove?
Yes, Bedgrove is covered. 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.
I let a flat near Stoke Mandeville station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Bedgrove, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. In a smaller place like Bedgrove, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Landlord and commercial work in Bedgrove
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What the job involves on each surface
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not paint over the new mastic
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Make sure water runs off the sill
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Bedgrove homes and the weather
London and the South East are among 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 live in an older home near Church of the Holy Spirit, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Bedgrove Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Stoke Mandeville station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
