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

Quoting for work in Maze Hill

These are the things that shape the price:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

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

To price the job accurately, we need a clear picture of the site. Send us:

  • Access details, including height
  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • Specification clauses that apply

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Sealant applicators in Maze Hill

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. If you are dealing with smeared sealant across finishes from a rushed job and frame sealant that has cracked, shrunk or pulled away, we can put it right, on movement joints in walls and floors, external facade joints and kitchen worktops and splashbacks alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Maze Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

The most common commercial job in Maze Hill is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Much of the planning for a London commercial job is about getting in and out: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. 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

Inside, cracked sealant around frames and window boards is common. The product depends on whether the joint will be painted.

For managing agents and facilities managers

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.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Maze Hill clients

Will our hotel in Maze Hill need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. Tell us how you issue work and we will fit in.

When something else is needed

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

  • Structural cracks or movement the joints weren’t designed for
  • Faulty windows rather than failed perimeter sealant
  • Water from a services leak rather than a joint

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Where we work in Maze Hill

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

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. In Maze Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  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. A final walk-round, then the 12-month guarantee applies.

Preparing the site

  • Let us know about inductions and permits
  • Send your site hours and access windows
  • Point out parking and an unloading spot
