Commercial sealant contractors for Felden sites

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

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Commercial sealant contractors in Felden

We have applied sealant on commercial sites for over 20 years: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. If you have mouldy silicone around WCs, urinals and vanity tops and weathered facade sealant that no longer flexes, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Felden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

The most common commercial job in Felden is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Places like Felden tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Questions we are asked in Felden

Will our hotel in Felden need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Does your area include sites such as Apsley Industrial Estate, near Felden?

Yes. Estates, retail parks and business parks around Felden, Apsley Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Can you handle sealant work across several sites?

Yes, we can. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.

Could the old sealant in an older building contain asbestos?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

Can you supply RAMS and insurance details?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Does commercial sealant work come with a guarantee?

A 12-month guarantee covers the workmanship. Looking after the joints as we advise helps them last.

Do you cover Felden?

Yes. We take on work across Felden.

Why act early in Felden

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why us?

  • One number for every site we cover
  • Standard and matched colours in many product ranges
  • Work to your specification and the manufacturer’s guidance
  • Work carried out by CSCS-carded applicators

Read what affects the cost or our accreditations.

What we can’t put right

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

  • Misted, cracked or failed glazing units (a glazier’s job)
  • A dripping trap, valve or pipe behind a fitting
  • Walls or slabs moving more than any sealant can take

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.

What we seal

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

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a site in Felden, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

Frontages, fit-outs and joints in Felden

The planned town of Hemel Hempstead is on Felden’s doorstep. Commercial buildings from the planned-town decades tend to carry joints from several refits, not all of them matching. Central London is about 22 miles from Felden. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

If you run a unit on an estate such as Apsley Industrial Estate (0.5 miles north-west of Felden), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. In a retail centre such as The Heights Shopping Centre, which lies north of Felden, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. For premises near Apsley station, which lies north-west of Felden, footfall is part of the plan: work is phased so shops and offices keep trading.

Felden is about 2 miles south of Hemel Hempstead, in Hertfordshire. Looking for commercial sealant contractors in Felden? We can help, as we do across Hertfordshire. Across Hertfordshire, 371 places are covered, including Felden. We also cover London, some 22 miles away.

Different surfaces, different methods

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, which matters when environmental health officers look at a kitchen. We seal to a neat, cleanable finish and work around service times you agree with us.

How the quote is worked out

To price the job, we consider:

  • Location, for remote and island sites
  • The total length or number of joints
  • Phasing around occupants
  • The size and state of each joint

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
