How we handle commercial sealant contractors in High Ongar
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we will plan around them; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on external facade joints, floor and threshold joints and kitchen worktops and splashbacks, and what we are called in for most is wall and floor joints that have lost their seal and frame sealant that has cracked, shrunk or pulled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in High Ongar, preparation and product choice get the time they need.
If you look after more than one building near High Ongar, the work can be planned as one programme, with one quote format and one point of contact.
Work in smaller places such as High Ongar tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered
Do you cover business parks and estates near High Ongar, such as Hallsford Bridge Industrial Estate?
Yes. Estates, retail parks and business parks around High Ongar, Hallsford Bridge Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can the sealant on our High Ongar premises match the finishes?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photos and we’ll confirm what’s available for the product.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Is it OK to apply fresh sealant over existing beads?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Is your work guaranteed?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes part of a day on a small job and longer where several buildings or phases are involved. For bigger or phased jobs, we’ll set out a timescale with the quote.
Commercial sealant contractors around High Ongar: what changes locally
High Ongar is about 21 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. High Ongar is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
If you run a unit on an estate such as Hallsford Bridge Industrial Estate, 0.9 miles south of High Ongar, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Whatever the building in High Ongar, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

What the job involves on each surface
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Old mastic that tests positive for asbestos
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Cost factors for sealant joints
Your fixed quote is built from the real scope. It takes account of:
- Which sealant the job calls for
- The site’s rules and procedures

- How much existing material needs removing
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

- Your programme or deadline
- Specification clauses that apply

When to bring in a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around High Ongar can be grouped with others nearby. You will have a fixed quote before work starts.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Preparing the site
- Tell staff and tenants when we’ll be in
- Send your site hours and access windows
