Mastic sealing in Maple End

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the job changes by surface

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Mastic sealing in Maple End

Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve estate-wide sealant that is simply worn out and window mastic that has split and shrunk, across communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints. Most enquiries from Maple End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Maple End, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

After the work

A few simple habits keep the new joints working:

  • Track which buildings were done and when
  • Share your contractor requirements early
  • Make mastic part of routine maintenance checks
  • Share the asbestos register when you send details

Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

What we’re called out for in Maple End

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Look out for the following:

  • Mastic failing across several blocks on an estate
  • Draughts at frames across a block
  • A mix of products and colours from past repairs
  • Repeated reactive repairs to the same buildings

Historic properties like Audley End House, 4.5 miles west of Maple End, show the age of some local stock, where frame mastic must suit soft brick or stone.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?
  • Their public liability cover
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

Cost factors for mastic joints

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How much existing material needs removing
  • The product specified
  • The size and state of each joint
  • Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Details that help us quote

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

  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Specification clauses that apply

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Maple End: questions and answers

Is Maple End too far out for you?

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

Will you take on work at estates like Ashdon Road Commercial Centre, close to Maple End?

Yes. Our area takes in Maple End and its surroundings, with estates and business parks such as Ashdon Road Commercial Centre included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Is mastic sealing guaranteed?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

For managing agents and facilities managers

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

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. For a building around Maple End, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Have the specification and drawings to hand

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Looking after buildings in and around Maple End

Maple End lies roughly 40 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Maple End included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

Site managers at schools like Radwinter Church of England Voluntary Aided Primary School can fit frame mastic into the summer works. For owners of several units at places like Ashdon Road Commercial Centre, which lies north-west of Maple End, one programme can deal with frame and external mastic across the lot.
