Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, 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 Sudbury Hill, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Tell us what induction or permit system the site runs
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Advice
How we handle construction mastic in Sudbury Hill
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. We work on cladding and panel joints, floor and skirting junctions and internal decorators’ caulk, and what we’re called in for most is internal caulk splitting as the building dries out and early adhesion failures on new external joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Sudbury Hill is the same: the right product in a properly prepared joint.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Sudbury Hill must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Is the mastic package guaranteed?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We are fully insured for public liability.
Why act early in Sudbury Hill
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. 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.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Looking after the joints
A few simple habits keep the new joints working:
- Brief the final clean team to avoid blades near sealant
- Record the products used in the O&M file
- Allow flexibility for external sealing in damp or cold weather
- Keep finished joints away from paint, plaster and scrapers
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It allows for:
- Whether old sealant has to be cut out first
- The product specified
- How accessible the joints are
- Working within restricted access windows
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Approximate linear metres or a joint schedule
- When you need the work done
- Anything awkward about access or site hours
- Specification clauses that apply
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What we’re called out for in Sudbury Hill
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Typical triggers for a call:
- Internal caulk splitting as the building dries out
- External joints sealed in damp or cold conditions that are now failing
- Frame perimeters left unsealed or poorly sealed
- Bath and shower joints scraped during the final clean
Units on estates such as Greenford Green Business Park, 1.1 miles south-west of Sudbury Hill, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
