Construction mastic in Aspley Guise, done properly

Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. If you’re dealing with inconsistent sealant finishes from plot to plot and window and door perimeters that won’t pass inspection, we can help, on cladding and panel joints, sanitary and kitchen joints and window and door perimeters alike. Most enquiries from Aspley Guise start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Around smaller places like Aspley Guise, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

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.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Frame gaps too wide for sealant, which the installer needs to correct
  • Faulty frames rather than failed sealant

If you are not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

  • Brick and block movement joints
  • Internal decorators’ caulk
  • Floor and skirting junctions
  • Window and door perimeters
  • Cladding and panel joints
  • Sanitary and kitchen joints

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Mastic packages on Aspley Guise sites

Aspley Guise has plenty of hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Aspley Guise is about 42 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For contractors refurbishing units at places like Rook Tree Farm Industrial Estate, which lies north of Aspley Guise, the mastic covers cladding panels, roller-door and window perimeters. On a healthcare site such as Milton Keynes University Hospital (4.6 miles west of Aspley Guise), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a school such as Aspley Guise Lower School, sealing has to be finished before term starts.

Aspley Guise is about 5 miles east of Bletchley, in Milton Keynes. Our applicators travel to Aspley Guise for work on mastic packages, handled exactly as we handle every other area.

Why deal with it now?

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. One visit to deal with every failing joint makes more sense than several trips to a place like Aspley Guise, rather than one at a time. Send photos of each area and we will quote for the lot.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • CHAS accredited contractor
  • 12 months’ guarantee on every job
  • Work to your specification and the manufacturer’s guidance
  • Fixed quotes based on photographs, drawings or a visit

Take a look at what affects the cost or our accreditations.

Aftercare for building managers

To get the most from the new sealant:

  • Use the product the specification names
  • Brief the final clean team to avoid blades near sealant
  • Don’t force external sealing on a damp or frosty day
  • Check frame gaps are within the sealant’s range before sealing

Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.

Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates, and we clear our waste as we work. If others near Aspley Guise need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we take quantities off the drawings and read through the specification.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

FAQs: Aspley Guise

Can work at a site such as The Open University fit around teaching?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is a smaller place like Aspley Guise outside your area?

No. Places such as Aspley Guise are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you work plot by plot or floor by floor?

Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start.

Is the mastic package guaranteed?

Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.

What accreditations do you hold?

CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can the sealant be colour-matched?

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 will confirm the colours available for the specified product.

How the quote is worked out

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

  • Location, for remote and island sites
  • The product specified
  • How much existing material needs removing
  • How accessible the joints are

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Access details, including height
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it
  • The postcode of the building

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
