About our mastic sealing in Newchurch

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. The enquiries we see most involve occupiers reporting cold air round windows and the same joint failures repeated across a portfolio, across communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Newchurch is the same: the right product in a properly prepared joint.

Around smaller places like Newchurch, 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.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in Newchurch

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.

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

  • Leaks at window and door perimeters
  • Draught complaints from residents or tenants
  • Brittle perimeter mastic across a building
  • Mastic failing across several blocks on an estate

Buildings close to stations like Sandown station, 2.1 miles to the east of Newchurch, are often flats over shops, with frame mastic to keep sound.

How to choose a sealant contractor

Your questions answered

Can being near the sea in Newchurch affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you cover business parks and estates near Newchurch, such as Langbridge Business Centre?

Yes. Our area takes in Newchurch and its surroundings, with estates and business parks such as Langbridge Business Centre included. Photos and a short description are enough for a first look.

Do you work for managing agents and housing associations?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Is Newchurch in your area?

Yes. Sites across Newchurch are covered, with one number for every area we cover.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Can you seal joints high up on a block?

It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.

How long will the new sealant last?

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.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Newchurch may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Tell staff and tenants when we’ll be in

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: 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.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Water coming in from the roof or rainwater goods
  • Asbestos-containing sealant, which we don’t remove
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)

If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • External wall and movement joints
  • Window and door perimeters on blocks
  • Balcony and threshold joints

Surface by surface

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. We plan around the site hours and access windows you give us.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler.

What affects the price in Newchurch

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

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Which sealant the job calls for

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Whether the building will be occupied during the work
  • The site address and postcode

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email the details over.

Mastic sealing around Newchurch: points for this area

With the shore within about 3 miles, Newchurch counts as a coastal location. On buildings near the shore, the side facing the weather typically needs its mastic renewed first. Newchurch sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Trustees of buildings like All Saints' Church can bring frame and external mastic into a planned maintenance list. If your remit includes a building such as Newchurch Primary School, frame and door mastic can be programmed for the holidays.
