Questions about Sellindge

Is Sellindge too small for you to travel to?

No. Places such as Sellindge are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can the sealant on our Sellindge premises match the finishes?

Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photos and we’ll confirm what’s available for the product.

What do you need from us to quote?

Start with whatever information is to hand. We follow up with questions or a visit where needed, then a fixed quote.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Commercial sealant contractors for commercial buildings in Sellindge

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Sellindge. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. The enquiries we see most involve hardened, chalky sealant on south-facing or exposed elevations and frame sealant that has cracked, shrunk or pulled away, on washrooms and tea points, floor and threshold joints and window and door perimeters. One point of contact handles commercial sealant work in Sellindge from the first photographs to the final walk-round, for single jobs and planned programmes alike.

If you look after more than one building near Sellindge, the work can be planned as one programme, with one quote format and one point of contact.

A job in a smaller place like Sellindge is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Sellindge are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Advice

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Sellindge can sit alongside others in a wider programme across Kent.

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. We can agree access arrangements and keyholder contacts beforehand.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Keep a record of which joints were resealed and when
  • Report cracked or peeling sealant early
  • Keep washroom and kitchen extraction working

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just speak to us on 01277 525 020 or send photos by email for a quote.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Shops, offices and hotels in and around Sellindge

Rainfall across the South East, Sellindge included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Less than 3 miles from Sellindge there are two named estates and business parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

For tenants and agents on sites such as Evegate Business Park, which lies west of Sellindge, office fit-outs, reception joints and window perimeters are the usual sealant work. Occupiers with premises at both Evegate Business Park and Mersham-le-Hatch Business Village could have the sealant at each handled under one quote.

Do you need commercial sealant contractors in Sellindge?

When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

Clients usually get in touch after noticing something like this:

  • Hardened, chalky sealant on south-facing or exposed elevations
  • Mouldy silicone around WCs, urinals and vanity tops
  • Wall and floor joints that have lost their seal
  • Frame mastic that has hardened and come away from the wall

For premises near Westenhanger station (1.6 miles south-east of Sellindge), footfall is part of the plan: work is phased so shops and offices keep trading.

Questions to ask before you appoint anyone

Different surfaces, different methods

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we will say so before sealing.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Structural cracks or movement the joints weren’t designed for
  • A dripping trap, valve or pipe behind a fitting

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