Windows and doors in Robertsbridge
Historic houses like Durhamford Manor (about 3.8 miles south-east) are a reminder that the area around Robertsbridge has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of 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 let a flat or house near Robertsbridge station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Robertsbridge United Reformed Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

How we handle glazing silicone in Robertsbridge
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you are dealing with sealant that was laid over old silicone and failed and water escaping where a screen meets the wall, we can put it right, whatever the surface.
Somewhere as small as Robertsbridge, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

Is Robertsbridge in your area for glazing silicone?

Will you come out to Robertsbridge?
Yes. Robertsbridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where is Mr Mastic based?

What guarantee do I get?
Every job comes with our one-year guarantee, and we are fully insured.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can I do 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.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Different surfaces, different methods
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
What affects the cost of glazing silicone
There’s no set price list. What we look at:
- Working hours on commercial sites
- The number and length of the joints
- The product the joint needs
- How many areas need sealing
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
What we need to know
There’s no need for technical detail. Just tell us:
- Where the property is
- Roughly how big the job is
- If someone has resealed it before
- How we’d reach the joints
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What sealant work can’t fix
We will always be straight with you, so here’s what sealant can’t fix:
- Leaks from the roof covering or flashing (a roofer’s job)
- Condensation trapped between two panes
- A sagging or failing conservatory roof
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Conservatory frames
- Glass-to-frame joints
- Rooflights
- Shower screens
- Glass-to-glass joints
- Glass balustrade bases
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What happens on the day
The work is kept neat and contained to the area we’re working on. The job generally takes a few hours for most jobs. Somewhere like Robertsbridge needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
When to call us in Robertsbridge
Heat and cold make glass and frames move, and they don’t move by the same amount. Over years, that movement tears the silicone.
Signs it’s time to call us include:
- Black or yellowed silicone on glass joints
- Failed joints on frameless glass
- Water tracking down the inner face of the glass
- Failed sealant around rooflight glass
For site and facilities teams at buildings such as Salehurst Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
