Construction mastic in Elmer, done properly

On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in Elmer, sealing plot by plot or floor by floor as areas are released. We work on cladding and panel joints, brick and block movement joints and floor and skirting junctions, and the failures we are asked to look at most are bath and shower joints scraped during the final clean and missed perimeter joints on a new elevation. A specialist sealant contractor works differently from a general builder: in Elmer, that means joint design, primers and backing rod as standard.

Around places like Elmer, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Building owners, agents and FMs in Elmer

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we’re called out for in Elmer

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.

Any of the following is a good reason to get the joints checked over:

  • Window and door perimeters that won’t pass inspection
  • Existing joints on a refurb that need cutting out and resealing
  • Sanitary sealant damaged by following trades
  • Oversized or tapered gaps around new frames

When a school such as Bishop Tufnell CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?
  • Who will actually carry out the work

FAQs: Elmer

Is Elmer off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is Rudford Industrial Estate, near Elmer, within your area?

Yes. Our area takes in Elmer and its surroundings, with estates and business parks such as Rudford Industrial Estate included. A few photographs and the unit address let us price the work.

What will the job cost?

Every job gets its own fixed quote. For yours, ring 01277 525 020 or email drawings and photos with a description of the work.

Is the mastic package guaranteed?

Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Damage to finishes by other trades after we have sealed
  • Oversized gaps that need packing or adjustment by others
  • Glazing units that are cracked or misted

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

What we seal

  • Cladding and panel joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Window and door perimeters
  • Sanitary and kitchen joints

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Elmer is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Send your site hours and access windows
  • Make sure the joints can be reached

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Leave it or put it right?

A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why us?

  • One contact handling all your sites
  • 12 months’ guarantee on every job
  • Commercial sealant work since 2005
  • Health and safety: CHAS accredited

Facades, frames and programmes in Elmer

Elmer lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Elmer lies roughly 54 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Hotel extensions and refits, at places such as Ancton House Hotel, under half a mile to the north of Elmer, typically run between busy periods, so the sealing is squeezed into short windows. Units on estates such as Rudford Industrial Estate (1.8 miles north-east of Elmer) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Elmer is about 3 miles east of Bognor Regis, in West Sussex. Anywhere in PO22, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 373 places across West Sussex fall within our area, Elmer among them. Our Portsmouth page has more on work in that area (20 miles or so).

If you need construction mastic in PO22, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Elmer Road, Ancton Lane and East Avenue, and sites on any of them can send details for a fixed quote. If your building is just outside Elmer, we cover Middleton-on-Sea (1 mile west), Bilsham (1 mile north), Atherington (1 mile north-east), Flansham (2 miles north-west) and Horsemere Green (2 miles north-east). Nearby towns on our patch include Worthing (9 miles east), Bognor Regis (3 miles west), Chichester (8 miles north-west), Selsey (9 miles south-west), Littlehampton (4 miles east) and Shoreham-by-Sea (15 miles east).

Around Elmer

In Elmer, that means premises near Felpham Community College. The nearest railway station is Ford station, roughly 2.9 miles north-east of the centre. A little further out are Bognor Regis Museum (3.1 miles west) and Bognor Regis War Memorial Hospital (2.9 miles west).

How the job changes by surface

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere.

Snagging before handover

The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
