About our commercial sealant contractors in Romford

Sometimes a split bead is a symptom rather than the cause. A leak near a frame edge can start in the frame, the cill or the cavity, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant. Most enquiries involve smeared sealant across finishes from a rushed job and hardened, chalky sealant on south-facing or exposed elevations, across window and door perimeters, movement joints in walls and floors and kitchen worktops and splashbacks. Whoever orders the work in Romford, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

A lot of what we do in Romford is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Travel to remote or island sites
  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • Any access equipment needed

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Specification clauses that apply
  • Clear photographs of the problem areas
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.

What happens if it’s left?

Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below. Dealing with it while the damage stops at the bead is the cheaper route. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

Pricing sealant joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

FAQs: Romford

Do you take on jobs in Romford where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it

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

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

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 if something is suspected, work stops until it’s tested.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

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.

Do you hold CHAS accreditation?

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

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Deal with small splits before they become leaks
  • Check sealant as part of routine building inspections
  • Keep a record of which joints were resealed and when
  • Keep abrasive pads and scrapers off resealed joints

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, speak to us on 01277 525 020 or email a schedule or drawings with a photo.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We’ll tell you which sealant joints need doing first and which can wait.

What the job involves on each surface

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Commercial premises in Romford

Romford 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. Romford has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

Units at retail parks like Rom Valley Retail Park (to the south of Romford) change hands and get refitted, with new joints at every frontage. For premises near Romford station, under half a mile south-east of Romford, footfall is part of the plan: work is phased so shops and offices keep trading. Shopping centres and retail parks such as Romford Shopping Hall (to the north of Romford) see a steady turnover of shop fits, each leaving joints where colour and finish matter.

Romford is about 12 miles west of Basildon, in Greater London. Anywhere in RM1, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Romford is one of 764 places in Greater London on our list for sealant joints. There’s a separate page for London, roughly 13 miles from Romford.

Commercial sites across RM1, RM7, RM11 and RM2 are covered. Buildings on High Street, Market Place and Market Link are within our area.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  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.

What we need from you

  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
