About our coloured sealant in Medstead

A colour-matched bead still has to work as a seal. Each joint is cleaned, backed to depth and tooled firmly onto both faces, with no shortcuts because it’s decorative. Clean masking and steady tooling give the sharp lines colour work needs. Most enquiries involve joints that need to match a new RAL frame colour and hotel refurbishments with a set colour scheme, on hotel bathrooms and public areas, powder-coated and anodised frames and office fit-out finishes. Whether you call it commercial sealant work, mastic application or joint sealing, in Medstead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Sealant jobs for businesses in a place the size of Medstead are often best grouped: frontage, staff facilities and window perimeters on one booking. That keeps travel and disruption down, and where colour matters on the frontage, we will confirm what’s available for the product.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

When to call us in Medstead

Sometimes the wrong colour went in at the start, or a substitute product was used. The joint may work perfectly but look out of place.

Look out for the following:

  • Previous reseals that don’t match the original
  • Fit-outs with a sealant colour in the specification
  • Untidy coloured beads with ragged edges
  • Sealant that no longer suits recoated frames

Offices and shops close to stations such as Alton station, 4.4 miles to the north-east of Medstead, tend to be busy all day, so sealant work is planned around opening hours.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the joint faces will be prepared and primed
  • Their pre-qualification and accreditations

What affects the price in Medstead

Each job is priced on its own details. The main factors are:

  • Which sealant the job calls for
  • Phasing around occupants
  • How much there is to seal
  • Induction, permit and paperwork requirements

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • The product your specification calls for

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?

Matching new joints to the existing ones is easier when the whole run is done together. Small repairs at different times rarely match, so a planned reseal often looks better value. For buildings in places like Medstead, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Medstead choose us

  • Fixed quotes based on photographs, drawings or a visit
  • Joints cleaned back to sound surfaces
  • Constructionline member for supplier checks
  • RAL and finish matching where the product range allows

Questions we’re asked in Medstead

Is Medstead too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Medstead, such as Mansfield Business Park?

Yes, sites like Mansfield Business Park are within our area, along with the rest of Medstead. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can we see a sample before the full job?

Yes. Where colour is critical, we can agree a short sample bead in a discreet spot. The colour can shift a little as it cures, so it’s worth checking in real light.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you use coloured sanitary silicone?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified before work starts.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. 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 Medstead is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Before we start on site

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Tell us your opening times and when work is allowed

Shops, offices and hotels in and around Medstead

Medstead is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it.
