Facade sealing for Goodnestone sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. For work around Goodnestone, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell staff and tenants when we will be in
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Facade sealing for commercial buildings in Goodnestone

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames, and the failures we are asked to look at most are perimeter sealant that has split or peeled away and discoloured or dirty facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Goodnestone, preparation and product choice get the time they need.

Construction in and around smaller places such as Goodnestone is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What the job involves on each surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.

Signs you need facade sealing in Goodnestone

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

What tends to prompt an enquiry:

  • Water coming in around window frames
  • Facade joints cracked through the middle
  • Draughts around frames and panels
  • Previous reseals run over old sealant

When units on a site such as Waterham Business Park (2 miles east of Goodnestone) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Before you book anyone

  • What site paperwork they can supply
  • The named product and why it was chosen
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?

Our contractor checklist

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Work on the window or framing system itself
  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Joints and surfaces we work on

Facade sealing in Goodnestone: the local picture

Goodnestone is within about 3 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Central London is about 46 miles from Goodnestone. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

On a healthcare site such as Whitstable and Tankerton Hospital, 5.8 miles north-east of Goodnestone, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a school such as Graveney Primary School, sealing has to be finished before term starts.

Goodnestone is about 2 miles east of Preston, in Kent. Businesses, contractors and managing agents in Goodnestone can call on us for facade joints, as part of our coverage of Kent. Across Kent, 931 places are covered, including Goodnestone. For work in that direction, see our London page (46 miles or so).

If your building is just outside Goodnestone, we cover Culmers (1 mile north-east), Graveney (1 mile north-east), Broom Street (1 mile north), Staplestreet (1 mile south-east) and Slutshole (1 mile south-east). Bigger towns within reach include Ashford (12 miles south), Canterbury (7 miles east), Sittingbourne (9 miles west), Whitstable (5 miles north-east), Herne Bay (9 miles north-east) and Minster (9 miles north-west).

Other landmarks nearby include Whitstable and Tankerton Hospital (5.8 miles north-east). Not far away are Blean Woods RSPB Reserve.

Owners, agents and contractors

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.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Questions we’re asked in Goodnestone

Our building in Goodnestone is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is a smaller place like Goodnestone outside your area?

Not at all. Goodnestone is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Do you replace failed glazing units?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Looking after the joints

For the best life from the joints:

  • Walk the elevations once or twice a year
  • Investigate damp beside windows promptly
  • Plan facade sealing alongside redecoration
  • Keep sills, gutters and drainage paths clear

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly with a compatible product.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
