Sand mastic in Egypt
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We’re often asked to deal with silicone on a period window that looks wrong and gaps where the frame meets the masonry, across tenement windows, stone surrounds and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Egypt is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window

What sand mastic looks like in Egypt
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Ebenezer Methodist Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- Decisions on consent for listed homes
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Brick reveals
- Sash and case windows
- Tenement windows
- Timber door frames
- Stone surrounds
- Period & listed homes
Why deal with it now?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Egypt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere as small as Egypt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or send us an email.
Advice
What affects the quote in Egypt
The price is agreed before any work begins. It takes into account:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number and length of the joints
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- The type of property
- Access, such as stairs, a lift or height
To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Questions from Egypt
Can you do sand mastic in Egypt?
Yes. Our work covers London and the South East, and Egypt is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Micheldever station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Should I use sand mastic or silicone?
We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
