FAQs: Singleton

Do you take on block-wide or estate-wide mastic work in Singleton?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

Is a smaller place like Singleton outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you work with property factors and landlords?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Mastic sealing for commercial buildings in Singleton

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. Site teams most often ask us about a mix of products and colours from past repairs and damp patches beside frames, on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. One point of contact handles commercial sealant work in Singleton from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For owners with a single building near Singleton, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Communal areas

Communal areas stay in use while we work. We work in sections so access is never blocked.

For owners and agents in Singleton

Singleton 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. At about 50 miles from central London, Singleton is within reach of the capital. 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.

If your remit includes a building such as Singleton CofE Primary School, frame and door mastic can be programmed for the holidays. Older community buildings, The Parish Church of the Blessed Virgin Mary among them, often have frames of mixed ages whose mastic varies. Historic properties like West Dean House (1.2 miles west of Singleton) show the age of some local stock, where frame mastic must suit soft brick or stone.

Singleton is about 5 miles north of Chichester, in West Sussex. We cover commercial sites throughout Singleton, whether it’s a single job or part of a planned programme. Across West Sussex, 373 places are covered, Singleton among them. Our Portsmouth page has more on work in that area, about 16 miles away.

We cover the PO18 postcode districts for mastic joints. If your site is on Downley Close, The Leys and Charlton Road or close by, send details and we’ll quote for mastic joints. We also cover Charlton (1 mile east), West Dean (1 mile west), East Dean (2 miles east), Cocking (3 miles north) and Heyshott (3 miles north-east) for mastic joints. Nearby towns on our patch include Bognor Regis (9 miles south), Chichester (5 miles south), Selsey (12 miles south), Littlehampton (12 miles south-east), Rustington (13 miles south-east) and Storrington (13 miles east).

Around Singleton

Locally, jobs take us to sites close to The Partridge Inn. Nearby you will also find Weald and Downland Gridshell (less than half a mile south-west) and Chichester Centre (4.5 miles south). Green spaces nearby include Levin Down and Kingley Vale National Nature Reserve.

Looking after the joints

To get the most from the new sealant:

  • Track which buildings were done and when
  • Prioritise elevations facing the weather
  • Check the asbestos register before any old mastic is disturbed
  • Make it easy for occupiers to report draughts

Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Leaks through the frame itself rather than the perimeter
  • Substrate edges that need repairing first
  • Water coming in from the roof or rainwater goods

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Singleton

  • Balcony and threshold joints
  • External wall and movement joints
  • Shopfronts below residential blocks

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Singleton can sit alongside others in a wider programme across West Sussex.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Singleton are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Have the specification and drawings to hand
  • Point out any areas we must not close
  • Let us know about inductions and permits

Cost factors for mastic joints

Before we quote, we look at:

  • Quantities, in metres or numbers
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • How accessible the joints are

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Any specification or named product
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or send details through our quote form to discuss it first.
