How we handle commercial sealant contractors in Upper Eashing

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. If you have gaps behind commercial kitchen worktops and sinks and black mould through washroom sealant that won’t clean off, we can put it right. For commercial sealant work in Upper Eashing, you deal with one contact from quote to sign-off, whether it’s one building or several.

Occupied buildings in Upper Eashing need the work phased: washrooms in turn, floors in sections and entrances kept open.

Work in smaller places such as Upper Eashing tends to come one building at a time: a pub kitchen, a hall, a small office. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

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

Your questions answered

Do hotels near Upper Eashing have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Is a smaller place like Upper Eashing outside your area?

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

Is the old sealant taken out first?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you work directly for building managers?

Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. We can work to your instruction process and site rules.

How the quote is worked out

We price every job individually. The main factors are:

  • Any access equipment needed
  • Quantities, in metres or numbers
  • How much existing material needs removing
  • 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.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Upper Eashing, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Flag any permit to work we will need
  • Send your site hours and access windows

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A failed roof covering or waterproofing membrane
  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)

If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.

Surfaces we seal

  • Kitchen worktops and splashbacks
  • Washrooms and tea points
  • Window and door perimeters
  • Floor and threshold joints
  • Movement joints in walls and floors
  • External facade joints

Common problems we fix in Upper Eashing

If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Typical triggers for a call:

  • Wall and floor joints that have lost their seal
  • Damp patches where an external joint has failed
  • Window and door perimeter joints that have cracked open
  • Smeared sealant across finishes from a rushed job

If you have premises on more than one site, say at Godalming Business Centre and Home Farm Business Park, one contractor and one quote can cover both.

What to look for in a quote

  • Their public liability cover
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

Commercial premises in Upper Eashing

Upper Eashing has a number of hotels close by, all within 2 miles. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let. Upper Eashing has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

Refits at hotels like The Kings Arms and Royal Hotel, 1.4 miles to the east of Upper Eashing, bring joints at vanity tops, bars and reception desks that guests see every day. Offices and shops close to stations such as Godalming station (1.1 miles east of Upper Eashing) tend to be busy all day, so sealant work is planned around opening hours.

Upper Eashing is about 5 miles south-west of Guildford, in Surrey. Anywhere in GU7, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Surrey, 379 places are covered, including Upper Eashing. Our Reading page has more on work in that area.

Commercial sites across GU7 are covered. If your site is on Eashing Lane and Lower Eashing or close by, send details and we’ll quote for sealant joints. We also cover Lower Eashing (1 mile north-west), Aaron's Hill (1 mile east), Norney (1 mile north-west), Milford (1 mile south) and Peper Harow (1 mile west) for sealant joints. Bigger towns within reach include Guildford (5 miles north-east), Woking (10 miles north), Camberley (11 miles north), Farnham (7 miles west), Dorking (14 miles east) and Frimley (10 miles north-west).

What happens if it’s left?

It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Around Upper Eashing, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
