Common problems we fix in Sandon
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.
These are often picked up first by site or facilities staff:
- Facade joints cracked through the middle
- Damp patches beside frames after rain
- Gaps between rainscreen or cladding panels
- Air leaks through failed facade joints
When a college such as Chelmsford College Princes Road Campus, 2.2 miles west of Sandon, builds or refurbishes, the mastic package usually has to fit around students and staff.
Before you book anyone
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled
- What level of public liability insurance do they hold?
- Will RAMS and insurance details be available?
How we handle facade sealing in Sandon
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. We work on window and door perimeters, cladding panel joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are water coming in around window frames and weathered joints at frame-to-structure perimeters. Looking for mastic applicators who cover Sandon? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a site near Sandon, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

FAQs: Sandon
Would you work within a site like Phoenix Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will you plan work around the academic year at somewhere like Anglia Ruskin University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Render or concrete edges that have broken away
- Work on the window or framing system itself
- Joints whose design needs changing by the specifier
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Surfaces we seal
- Stone and brick facade joints
- Coping and flashing joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Shopfront frames
- Window and door perimeters
Maintenance after handover
To get the most from the new sealant:
- Ask about asbestos in pre-2000 mastic
- Combine resealing with other works that need access
- Keep the sealant details on the building file
- Walk the elevations once or twice a year
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Advice
New build and refits around Sandon
Sandon lies roughly 30 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, Sandon included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
New wings at hospitals like Phoenix Hospital (to the south-west of Sandon) bring long runs of window and panel joints to seal. Building work at universities like Anglia Ruskin University, 2.9 miles to the north-west of Sandon, is often timed for the summer, mastic included.
