Construction mastic in Bletchley and Fenny Stratford, done properly

Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Bletchley and Fenny Stratford, send drawings and the specification through our quote form. The enquiries we see most involve frame perimeters left unsealed or poorly sealed and different trades sealing to different standards, on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions. A single leaking joint is often how a building in Bletchley and Fenny Stratford first comes to us: we look at the rest while we’re there and tell you what we find.

Many towns of Bletchley and Fenny Stratford’s size have older buildings being converted or extended, which puts new frames and panels against old brick, stone or render. Getting the product and primer right for both faces is what keeps those joints sound.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Bletchley and Fenny Stratford clients

Can you work on a hospital site such as Milton Keynes University Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you cover business parks and estates near Bletchley and Fenny Stratford, such as South Caldecotte Business Park?

Yes. We cover Bletchley and Fenny Stratford and the area around it, including industrial estates, business parks and retail parks such as South Caldecotte Business Park. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Do you cover Bletchley and Fenny Stratford?

Yes. Sites across Bletchley and Fenny Stratford are covered.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

What hours do you work?

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

What we’re called out for in Bletchley and Fenny Stratford

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.

Clients typically get in touch after noticing one or more of the following:

  • Early adhesion failures on new external joints
  • Perimeter gaps outside the sealant’s range
  • Old sealant on a refurbishment that needs stripping before new work
  • Internal caulk splitting as the building dries out

For a contractor at a hotel such as The Swan Hotel, which lies north-east of Bletchley and Fenny Stratford, the mastic often has to be finished before a reopening date.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Their pre-qualification and accreditations
  • How they’ll work around occupants
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Cost factors for mastic packages

Before we quote, we look at:

  • Access and working height
  • The site’s rules and procedures
  • Removal of failed or old sealant
  • The total length or number of joints

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

However big the job, the same details help:

  • Clear photos of the problem areas
  • The site address and postcode
  • When you need the work done
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email a schedule or drawings.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

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.

Why deal with it now?

Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. In Bletchley and Fenny Stratford, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • Colours confirmed for the specified product
  • A Constructionline member, so easy to vet
  • Public liability insurance in place
  • CHAS accredited

See what affects the cost and our accreditations.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Frames fitted out of tolerance
  • Specifying the product where the designer hasn’t
  • Defective windows, doors or glazing units (the supplier or installer’s job)

If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Surfaces we seal

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

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If you have more than one building in Bletchley and Fenny Stratford, they can often be done on the same visit. Give us your access times and we will fit the work in.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • Arrange parking or a loading space
