Construction mastic for businesses in Fenny Stratford

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Fenny Stratford can form part of a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Construction mastic for commercial buildings in Fenny Stratford

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. Our aim is joints that pass at the first inspection, whatever the size of the scheme. Site teams most often ask us about oversized or tapered gaps around new frames and sanitary sealant damaged by following trades, on window and door perimeters, internal decorators’ caulk and floor and skirting junctions. For commercial sealant work in Fenny Stratford, you deal with one contact from quote to sign-off, whether it’s one building or several.

In a smaller place such as Fenny Stratford, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Fenny Stratford: questions and answers

Does your area include sites such as South Caldecotte Business Park, near Fenny Stratford?

Yes, sites like South Caldecotte Business Park are within our area, along with the rest of Fenny Stratford. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is a smaller place like Fenny Stratford outside your area?

Not at all. Fenny Stratford is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Are you fully insured?

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

When can you be on site?

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

Are you CHAS accredited?

CHAS and Constructionline are both in place, and each applicator is CSCS-carded. We are fully insured for public liability.

Mastic packages on Fenny Stratford sites

Fenny Stratford 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 we time external mastic for dry faces and agree it with the site team. A number of hotels sit less than 2 miles from Fenny Stratford. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

University estates such as The Open University (to the north of Fenny Stratford) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Further education sites such as Milton Keynes College (to the north-west of Fenny Stratford) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hospital estates such as Milton Keynes University Hospital (to the north-west of Fenny Stratford) 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.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Fenny Stratford is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. First we take quantities off the drawings and read through the specification.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

Different surfaces, different methods

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which with colours matched to the frame where needed.

What affects the price in Fenny Stratford

Before we quote, we look at:

  • Location, for remote and island sites
  • Any access equipment needed
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Specifying the product where the designer hasn’t
  • Oversized gaps that need packing or adjustment by others
  • Approving fire stopping as compliant

Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Where we work in Fenny Stratford

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

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
