Facade sealing in High Ongar
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We build that into the programme and tell you if the forecast changes the plan. We work on perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints, and the usual reasons a site gets in touch are leaks at window and door perimeters and failed sealant on precast panel joints. Most enquiries from High Ongar start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like High Ongar, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Brief window cleaners about newly sealed joints
- Keep sills, gutters and drainage paths clear
- Record the product and colour used on each elevation
- Check the asbestos register before old mastic is disturbed
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like High Ongar are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space

Quoting for work in High Ongar
A fixed quote reflects the actual work. It allows for:
- The total length or number of joints
- Phasing around occupants
- Distance, for remote addresses
- Backing rod, priming and other preparation
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Whether the building will be occupied during the work
- Access details, including height
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Questions we are asked in High Ongar
Can the mastic package for our job in High Ongar follow the site programme?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is High Ongar off your patch?
No. Places such as High Ongar are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings.

Facades, frames and programmes in High Ongar
At about 21 miles from central London, High Ongar is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. High Ongar sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Projects at schools like High Ongar Primary School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Hallsford Bridge Industrial Estate, which lies south of High Ongar, the mastic covers cladding panels, roller-door and window perimeters.

How the job changes by surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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.
What happens if it’s left?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Halls, stores and units around places like High Ongar may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
