How we handle construction mastic in Penton Hook

Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Penton Hook, send drawings and the specification through our quote form. If you have failed sealant in an existing building being refurbished and mastic snags holding up handover, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Penton Hook it comes down to the same thing: the right product in a properly prepared joint.

In the countryside around places like Penton Hook, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

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

How the job changes by surface

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which, and colour-matched products can be used where the frame is on show.

Fire-rated sealant where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we will tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Penton Hook can form part of a wider programme across Surrey.

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.

Why it’s worth doing now in Penton Hook

On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. We will say so if a frame itself is the problem. One visit to deal with every failing joint makes more sense than several trips to a place like Penton Hook, rather than one at a time. Photos of every joint help us quote for the whole job.

A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Why clients in Penton Hook choose us

  • A range of standard colours, depending on the product

Site staff or a sealant specialist?

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

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.

Building and refurbishing in Penton Hook

Penton Hook is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Penton Hook has plenty of hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

New units and refits on sites such as Thorpe Industrial Estate, 1.4 miles west of Penton Hook, need their panel and perimeter joints sealed to the specification. Building work at universities like Royal Holloway University, 3.1 miles north-west of Penton Hook, is often timed for the summer, mastic included. For a contractor working at a hospital such as St Peter's Hospital A&E, which lies south-west of Penton Hook, perimeter and facade sealing is planned around patients and deliveries.
