Sand mastic in Odiham
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with mastic worn away on windows facing the weather and cement or filler used on old window joints that has cracked, we can put it right.
Homes around Odiham range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
There’s a 12-month guarantee on every job, whatever its size.

Odiham questions
Can you do sand mastic in Odiham?
Yes. We work across London and the South East, and Odiham is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Do you work for landlords with property near Hook station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In a smaller place like Odiham, 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.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

What affects the quote in Odiham
You will get a clear quote before we start. It’s based on:
- Mould in or behind the old joints
- The old material and how stubborn it is
- Whether the work is at height
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Photos by email, if that is easy
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
Should I try it myself first?
What a professional job adds is preparation and the right 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Odiham homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Hook station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Mayhill Junior School? Then its window and door frames need their mastic kept sound, just like a home’s.

Honest limits
In fairness, there are a few things sealant will not fix:
- Putty and glazing repairs
- Whether work needs listed building consent
- Sashes that rattle, stick or won’t open

When to call us in Odiham
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
For an older house near a landmark such as All Saints Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
