Mastic sealing in Steep Marsh
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and what we’re called in for most is old repairs sealed over failed mastic and open joints in brickwork or panels. One point of contact handles commercial sealant work in Steep Marsh from the first photos to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Steep Marsh, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why it’s worth doing now in Steep Marsh
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Older rural buildings around Steep Marsh move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Aftercare for building managers
For the best life from the joints:
- Keep a record of when each building was resealed
- Avoid piecemeal callouts where you can
- Make it easy for occupiers to report draughts
- Mention RAMS, insurance or CSCS requirements up front
Our workmanship is covered for 12 months, so report any failure in that time. 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 and work down the list.
Mastic sealing around Steep Marsh: what changes locally
Steep Marsh lies roughly 49 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Rainfall across the South East, Steep Marsh included, is lower than in many parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first.
If your remit includes a building such as Steep Church of England Voluntary Controlled Primary School, frame and door mastic can be programmed for the holidays. Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list. Landlords with units on estates such as Upper Adhurst Industrial Park, 1.8 miles east of Steep Marsh, can bring frame, door and external mastic across several units into one programme.

Advice
Questions about Steep Marsh
Is Steep Marsh off your patch?
Not at all. Steep Marsh is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Upper Adhurst Industrial Park, close to Steep Marsh?
Yes, sites like Upper Adhurst Industrial Park are within our area, along with the rest of Steep Marsh. Send details of the unit and the work through our quote form for a quick quote.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How do you reach windows on upper floors?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Cost factors for mastic joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Quantities, in metres or numbers
- How much existing material needs removing
- Location, for remote and island sites
- Site requirements such as inductions and permits
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- A wide shot and a close-up of the area
- The product your specification calls for
- When you need the work done
- The postcode of the building
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or use the quote form.
Surface by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.
Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
