Facade sealing for businesses in Alscot

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

Facade sealing for commercial buildings in Alscot

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around. We work on stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure, and what we’re called in for most is perimeter joints where frames meet the structure and air leaks through failed facade joints. Searching for sealant specialists in Alscot? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For a site near Alscot, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

Building owners and contractors get the same cover: 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.

Common questions from Alscot clients

Can you keep pace with our programme in Alscot?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Alscot off your patch?

Not at all. Alscot is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

How the job changes by surface

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.

Quoting for work in Alscot

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • The postcode of the building
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Mastic packages on Alscot sites

Alscot is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Alscot lies roughly 36 miles out from central London. 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 Princes Risborough Primary School, usually run to the summer holidays, mastic included. Hospital estates such as The Paddocks Hospital, 0.6 miles to the south-east of Alscot, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Alscot is about 6 miles east of Thame, in Buckinghamshire. Across the HP27 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 308 places across Buckinghamshire fall within our area, including Alscot. Sites around Oxford have their own page, about 17 miles away.

If you need facade sealing in HP27, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Just outside Alscot, we also work in Monks Risborough (1 mile east), Princes Risborough (1 mile south-east), Longwick (1 mile west), Askett (1 mile north-east) and Meadle (1 mile north). A short drive away, we cover Aylesbury (6 miles north), High Wycombe (8 miles south-east), Chesham (10 miles east), Marlow (11 miles south), Amersham (11 miles east) and Beaconsfield (12 miles south-east).

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Rural sites near Alscot may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Make sure the joints can be reached
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send details through our quote form.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Specialist high-level access methods
  • Replacing glass or failed glazing units
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
