Mastic sealing across Rusper

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Questions we are asked in Rusper

Do you cover business parks and estates near Rusper, such as Holmbush Potteries Industrial Estate?

Yes, sites like Holmbush Potteries Industrial Estate are within our area, along with the rest of Rusper. Photos and a short description are enough for a first look.

Will you take on a block within reach of Faygate station?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Which sealant will you use?

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.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Can you reseal a whole block or estate?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Mastic sealing in Rusper, done properly

Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. The enquiries we see most involve mastic failing across several blocks on an estate and open joints in brickwork or panels, on balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks. Most enquiries from Rusper start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For buildings around smaller places like Rusper, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Rusper can form part of a wider programme across West Sussex.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Quoting for work in Rusper

Quotes vary with the job. It mainly depends on:

  • The total length or number of joints
  • How accessible the joints are
  • Distance, for remote addresses
  • The site’s rules and procedures

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Your programme or deadline
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, phone 01277 525 020 or email us.

For owners and agents in Rusper

Rusper sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. At about 27 miles from central London, Rusper is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

For owners of several units at places like Holmbush Potteries Industrial Estate (2.4 miles south-east of Rusper), one programme can deal with frame and external mastic across the lot. For agents with blocks near Faygate station, which lies south of Rusper, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Rusper is about 4 miles west of Crawley, in West Sussex. Rusper sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 373 places in West Sussex, from busy centres to rural villages. Brighton is covered too, around 21 miles from Rusper.

We cover the RH12 postcode districts for mastic joints. For a building on High Street, Cooks Mead and Chalice Walk or nearby, we can quote for mastic joints. If your building is just outside Rusper, we cover Lambs Green (1 mile east), Ifieldwood (2 miles east), Russ Hill (3 miles north-east), Bewbush (3 miles south-east) and Cudworth (3 miles north). Nearby towns on our patch include Crawley (4 miles east), Horsham (4 miles south-west), Haywards Heath (12 miles south-east), Burgess Hill (13 miles south-east), East Grinstead (12 miles east) and Broadfield (4 miles south-east).

What the job involves on each 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.

Commercial and mixed-use buildings

Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we will plan around them.

When to call us in Rusper

Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

If one of these sounds familiar, it’s time for a closer look:

  • Movement joints with sealant missing
  • Old repairs sealed over failed mastic
  • Window mastic that has split and shrunk
  • Draught complaints from residents or tenants

Trustees of buildings like St Mary Magdalene church can bring frame and external mastic into a planned maintenance list.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Their public liability cover
  • The named product and why it was chosen
  • How the existing material will be dealt with

Our contractor checklist

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. If others near Rusper need work, visits can be combined. A fixed quote is given before anything starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
