Commercial sealant contractors in Roehampton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Do you need commercial sealant contractors in Roehampton?

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Look out for the following:

  • Sanitary sealant that has gone black and patchy
  • Untidy joints in a reception, shop floor or lobby
  • External beads that have gone brittle and cracked
  • Gaps behind commercial kitchen worktops and sinks

In a retail centre such as Kew Retail Park (2.4 miles north-west of Roehampton), new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • What the guarantee covers, and for how long
  • How they’ll work around occupants
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Commercial sealant contractors in Roehampton

Inside a commercial building, sealant does a lot of quiet work: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. Site teams most often ask us about frame sealant that has cracked, shrunk or pulled away and mouldy silicone around WCs, urinals and vanity tops, on kitchen worktops and splashbacks, washrooms and tea points and external facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Roehampton is the same: the right product in a properly prepared joint.

Multi-site clients with buildings in and around Roehampton can put several sites on one programme, with one quote format and one point of contact.

Buildings in a London area such as Roehampton rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Roehampton

Can you work at a site such as Chartwell Business Park, by Roehampton?

Yes. We cover Roehampton and the area around it, including industrial estates, business parks and retail parks such as Chartwell Business Park. Photos and a short description are enough for a first look.

Does a hotel in Roehampton need to shut while its sealant is renewed?

In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is it OK to apply fresh sealant over existing beads?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.

How is commercial sealant work priced?

Send photographs, drawings or a list of locations. Where we need to see it, we will arrange a site visit, then send a fixed quote.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What Roehampton’s businesses ask us to seal

Less than 3 miles from Roehampton there are at least three named estates and business parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies. A 2-mile radius around Roehampton takes in a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.

If you run an office at a site such as Chartwell Business Park, 1.9 miles east of Roehampton, the sealant at reception desks, tea points and frames ages with each fit-out. A business with units at Chartwell Business Park and Hurlingham Business Park needn’t use two contractors for its sealant.

Surface by surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • A failed roof covering or waterproofing membrane
  • Misted, cracked or failed glazing units (a glazier’s job)
  • Old mastic that tests positive for asbestos

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

Joints and surfaces we work on

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

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a job in Roehampton, access comes first. Give us the hours we can be on site and we will schedule to suit.

  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. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.
