Questions about High Leigh
Is Hilgrove Business Park, near High Leigh, within your area?

Is High Leigh off your patch?
Not at all. High Leigh is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
About our mastic sealing in High Leigh
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. Most enquiries involve open joints in brickwork or panels and no planned programme for sealant, across window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: in High Leigh, that means joint design, primers and backing rod as standard.
In and around smaller places like High Leigh, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
A 12-month guarantee applies to all our work in Hertfordshire. If an installation problem shows up, phone 01277 525 020 or email drawings and photos and we will arrange a return visit.

After the work
Keep the joints in good shape with a few simple steps:
- Protect low-level joints in entrances
- Avoid piecemeal callouts where you can
- Include mastic in your cyclical inspections
- Make it easy for occupiers to report draughts
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: 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.

Mastic sealing in High Leigh: the local picture
Central London is about 18 miles from High Leigh. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. High Leigh is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Trustees of buildings like Church of St Catherine & St Paul can bring frame and external mastic into a planned maintenance list. Landlords with units on estates such as Hilgrove Business Park, 2.2 miles to the south-east of High Leigh, can bring frame, door and external mastic across several units into one programme. If your remit includes a building such as Westfield Community Primary School, frame and door mastic can be programmed for the holidays.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around High Leigh, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.

Before we start on site

- Confirm the product named in the specification

Advice
How the quote is worked out
We price every job individually. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Travel to remote or island sites
- The size and state of each joint
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The site address and postcode
- The product your specification calls for
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Surface by surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
