Construction mastic across Bix

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

Construction mastic in Bix, done properly

The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you have mastic snags holding up handover and caulk cracking where joints are moving more than expected, we can help. Looking for mastic applicators who cover Bix? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a site near Bix, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the job changes by surface

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services, and we will tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

Window and door perimeters

Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.

Why it’s worth doing now in Bix

Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. One visit to deal with every failing joint makes more sense than several trips to a place like Bix, rather than one at a time. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why appoint us

  • Fully insured, including public liability cover
  • One contact handling all your sites
  • A Constructionline member, so easy to vet
  • Fixed quotes based on photos, drawings or a visit

Owners, agents and contractors

Whether you’re 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.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

New build and refits around Bix

At about 37 miles from central London, Bix is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Bix included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

For a contractor working at a hospital such as Townlands Memorial Hospital (2.3 miles south-east of Bix), perimeter and facade sealing is planned around patients and deliveries. With historic properties like Greys Court (to the south of Bix) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Bix is about 6 miles north of Caversham, in Oxfordshire. Any commercial site in Bix is covered. Across Oxfordshire, 423 places are covered, Bix among them. We also cover Reading, around 8 miles from Bix.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Bix need work, visits can be combined. You will have a fixed quote before work starts.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Cost factors for mastic packages

To price the job, we consider:

  • The total length or number of joints
  • Whether the work must be split into stages
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • The product your specification calls for
  • Access details, including height
  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or use the quote form.

Questions we’re asked in Bix

Can you take on a job at a hospital such as Townlands Memorial Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Bix too small for you to travel to?

Not at all. Bix is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.

Which sealant will you use?

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 long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Site staff or a sealant specialist?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
