About our facade sealing in Catslip

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on stone and brick facade joints, shopfront frames and window and door perimeters, and what we’re called in for most is previous reseals run over old sealant and facade joints cracked through the middle. One point of contact handles commercial sealant work in Catslip from the first photos to the final walk-round, whether it’s one building or several.

In the countryside around places like Catslip, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facade sealing around Catslip: points for this area

Rainfall across the South East, Catslip included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Catslip is about 38 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

Units on estates such as Vanalloys Business Park (to the south-west of Catslip) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Historic houses such as Greys Court (to the south-east of Catslip) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Hotel extensions and refits, at places such as The White Hart Hotel, 0.5 miles to the west of Catslip, normally run between busy periods, so the sealing is squeezed into short windows.

Catslip is about 7 miles north of Caversham, in Oxfordshire. Any commercial site in Catslip is covered, for single jobs and planned programmes alike. We work across 423 places in Oxfordshire. For work in that direction, see our Reading page (9 miles or so).

  • Damaged frames that need replacing

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.

What we seal

Questions we’re asked in Catslip

Is Catslip too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Vanalloys Business Park, near Catslip?

Yes. We cover Catslip and the area around it, including industrial estates, business parks and retail parks such as Vanalloys Business Park. A few photographs and the unit address let us price the work.

Do you provide access for facade work?

We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

Who decides which product is used?

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.

Do you hold CHAS accreditation?

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

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What do you charge?

Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or email a schedule or drawings.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around Catslip can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

Related advice

Why act early in Catslip

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Around Catslip, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why choose Mastic Doctor in Catslip

  • Fully insured
  • Colour agreed before work starts
  • Fixed quotes based on photos, drawings or a visit
  • Matching to RAL references, product permitting

How the job changes by surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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, which is what makes a joint last.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • How accessible the joints are
  • The product specified
  • The size and state of each joint
  • Distance, for remote addresses

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • The asbestos register, for older buildings
  • The product your specification calls for
  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.
