Quoting for work in Nuthurst
To price the job, we consider:
- Removal of failed or old sealant
- How accessible the joints are
- Induction, permit and paperwork requirements
- Joint width, depth and condition
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The site address and postcode
- Drawings or a marked-up plan, if available
- When you need the work done
- What the building is and how it’s used
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or email us.
Mastic sealing in Nuthurst, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. Most enquiries involve occupiers reporting cold air round windows and movement joints with sealant missing, across external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms. For commercial sealant work in Nuthurst, you deal with one contact from quote to sign-off, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Nuthurst tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

What we’re called out for in Nuthurst
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Most enquiries start with something like this:
- Estate-wide sealant that is simply worn out
- Brittle perimeter mastic across a building
- Movement joints with sealant missing
- Damaged joints in communal entrances and corridors
If you look after a block within reach of Horsham station, 3.1 miles to the north of Nuthurst, frame and balcony mastic can be renewed on one programme.

Maintenance after handover
After handover, these steps help:
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
- Check sealant joints during planned building inspections
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
Questions about Nuthurst
Do you work for managing agents with blocks near Horsham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Southwater Business Park, close to Nuthurst?
Yes, sites like Southwater Business Park are within our area, along with the rest of Nuthurst. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you work in Nuthurst?
Yes. Sites across Nuthurst are covered.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaks through the frame itself rather than the perimeter
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
Planned mastic for Nuthurst portfolios
Nuthurst lies roughly 34 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Nuthurst is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Schools and community buildings such as St Andrew's CofE Primary School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as The Parish Church of St Andrew are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What the job involves on each surface
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
