Facade sealing in Spelsbury

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Spelsbury can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Send any specification or drawings in advance

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Facade sealing in Spelsbury, done properly

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and what we are called in for most is damp patches beside frames after rain and unsightly perimeter sealant on a visible elevation. Looking for mastic applicators who cover Spelsbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Sites around smaller places like Spelsbury can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Installing or repairing glazing systems
  • Render or concrete edges that have broken away
  • Damp caused by condensation inside the building

If in doubt, phone 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Cladding panel joints
  • Window and door perimeters
  • Coping and flashing joints
  • Stone and brick facade joints

Mastic packages on Spelsbury sites

Spelsbury sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. At about 66 miles from central London, Spelsbury is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

School extensions, at buildings such as Chadlington Church of England Primary School, normally run to the summer holidays, mastic included. New units and refits on sites such as Southill Business Park (to the south of Spelsbury) need their panel and perimeter joints sealed to the specification.

Spelsbury is about 7 miles north of Witney, in Oxfordshire. Looking for facade sealing in Spelsbury? We can help, as we do across Oxfordshire. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages. We also cover Oxford, around 15 miles from Spelsbury.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Building owners and managing agents use us on everything from one building to a spread of sites around Spelsbury. Several sites can go on one quote, which keeps the paperwork simple.

What affects the price in Spelsbury

A fixed quote reflects the actual work. It allows for:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Access and working height
  • Location, for remote and island sites

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.

Aftercare for building managers

After handover, these steps help:

  • Keep sills, gutters and drainage paths clear
  • Add perimeter sealant to planned maintenance checks
  • Don’t wait for a second leak before calling
  • Avoid patch repairs on failed facade joints

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

Surface by surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

Common questions from Spelsbury clients

Is Spelsbury off your patch?

No. Places such as Spelsbury are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can the mastic package for our job in Spelsbury follow the site programme?

Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

How do I request a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
