Windows and doors in Ranmore Common
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Polesden Lacey (about 1.2 miles north) nearby, there’s older building stock in the area around Ranmore Common 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.
Managing a site like Surrey Hills All Saints Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Barnabas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work starts. The work generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Ranmore Common needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Why it’s worth doing now in Ranmore Common
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Ranmore Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear price before work begins.

Your questions about window mastic in Ranmore Common
Can you help a landlord with a rental near Dorking West station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Can you do window mastic in Ranmore Common?
Yes. Our work covers London and the South East, and Ranmore Common is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
How long will my window job take?
The work takes a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
How the job changes by surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
How we quote for window mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The size of the job
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel

When to call us in Ranmore Common
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
It’s worth asking for a quote if you see:
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
Rented homes near Dorking West station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
