Different surfaces, different methods
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
About our construction mastic in New Alresford
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. Our aim is joints that pass at the first inspection, whatever the size of the scheme. If you have missed perimeter joints on a new elevation and a long mastic snag list close to completion, we can put it right, on sanitary and kitchen joints, internal decorators’ caulk and brick and block movement joints alike. A single leaking joint is often how a building in New Alresford first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a contractor on a smaller site near New Alresford, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Maintenance after handover
After handover, a little attention goes a long way:
- Allow flexibility for external sealing in damp or cold weather
- Stick to the specified sealant rather than a generic substitute
- Ask for joint and product checks before the package is urgent
- Don’t schedule sealing before decorators and flooring are done
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is New Alresford too small for you to travel to?
Not at all. New Alresford is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can you fit around our programme?
We work to your programme. Share the release dates and we’ll match our work to them.

Yes. A group of buildings can go on one quote, with one point of contact.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Building and refurbishing in New Alresford
A 2-mile radius around New Alresford takes in a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. New Alresford lies roughly 54 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
Hotels like The Swan Hotel, less than half a mile north-east of New Alresford, rarely close for long, so refurbishment mastic is phased floor by floor. Older buildings in the area around New Alresford, such as Hinton Ampner House (3 miles south of New Alresford), need care when sealed: the product has to suit soft or historic materials.
New Alresford is about 7 miles east of Winchester, in Hampshire. Across the SO24 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, New Alresford among them. Southampton is covered too, some 15 miles away.

General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in New Alresford, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.

Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. We cut out and redo the joint properly. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What we’re called out for in New Alresford
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Any of the following is a good reason to get the joints checked over:
- Early adhesion failures on new external joints
- Frame gaps too wide for sealant alone
- Snag items on joints that need redoing before handover
- Different trades sealing to different standards
For contractors at a school such as Sun Hill Junior School, sealing has to be finished before term starts.
What your quote should include
- How the joint faces will be prepared and primed
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
- Whether their applicators hold CSCS cards
