Commercial sealant contractors in Tower Hill

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Commercial sealant contractors in Tower Hill, done properly

Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas. If the joints need seeing in person, a site visit comes first. We work on window and door perimeters, floor and threshold joints and external facade joints, and the failures we are asked to look at most are frame mastic that has hardened and come away from the wall and greasy, split joints in a kitchen or tea point. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tower Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

A job in a smaller place like Tower Hill is usually a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Why act early in Tower Hill

On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation. It shows over the following seasons rather than at handover. Older rural buildings around Tower Hill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • CHAS accredited
  • Old sealant cut out, never sealed over
  • A Constructionline member, so easy to vet
  • Fully insured, including public liability cover

Take a look at what affects the cost and our accreditations.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few hours for one area, or a planned series of visits across a bigger building, and we clear our waste as we work. If others near Tower Hill need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. We strip the failed bead and prepare both faces of the joint.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we’ll need
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: 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, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Your questions answered

Is a smaller place like Tower Hill outside your area?

No. Places such as Tower Hill are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Must a hotel around Tower Hill close while you 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.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What do you need from us to quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.

Do you work directly for building managers?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How the job changes by surface

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. 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.

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.

Commercial clients in Tower Hill

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Frontages, fit-outs and joints in Tower Hill

The area within 2 miles of Tower Hill holds several hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. Tower Hill sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Sites a few miles apart, such as Tanbridge Retail Park and Broadbridge Retail Park, can share one programme and one point of contact. A hotel such as The King's Head Hotel, 0.8 miles north-east of Tower Hill, shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Shops and cafés around stations like Christs Hospital station (0.9 miles west of Tower Hill) trade from early, so work is timed around them.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

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

If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

Joints and surfaces we work on

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