Construction mastic for businesses in Hogpits Bottom

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

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take 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.

Construction mastic for commercial buildings in Hogpits Bottom

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can usually carry on while the outside waits. Site teams most often ask us about new external sealant already peeling away and existing joints on a refurb that need cutting out and resealing, on internal decorators’ caulk, window and door perimeters and brick and block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hogpits Bottom is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In the countryside around places like Hogpits Bottom, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Do you need construction mastic in Hogpits Bottom?

Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.

Any of the following is a good reason to get the joints checked over:

  • Early adhesion failures on new external joints
  • Frame perimeters left unsealed or poorly sealed
  • Internal caulk splitting as the building dries out
  • Different trades sealing to different standards

Older buildings in the area around Hogpits Bottom, such as Chenies Manor House, 2 miles to the south of Hogpits Bottom, need care when sealed: the product has to suit soft or historic materials.

Our contractor checklist

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Joint design decisions that belong to the architect or engineer
  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Joints damaged after sign-off by following trades

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Surfaces we seal

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

Leave it or put it right?

On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal, which is a much smaller cost. If the frame is life-expired, we’ll tell you. Older rural buildings around Hogpits Bottom move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why appoint us

  • Constructionline member
  • Joints cleaned back to sound surfaces
  • Colour agreed before work starts
  • Specification-led, product-correct work

Questions about Hogpits Bottom

Does your area include sites such as Boughton Business Park, near Hogpits Bottom?

Yes, sites like Boughton Business Park are within our area, along with the rest of Hogpits Bottom. Photos and a short description are enough for a first look.

Is Hogpits Bottom too far out for you?

No. Places such as Hogpits Bottom are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Do you use the sealant named in the specification?

We follow the specified sealant and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
