Mastic packages on Shirley sites
The sea is no more than about 1 mile from Shirley. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. There are a good number of hotels within about 2 miles of Shirley. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Further education sites such as Richard Taunton Sixth Form College (to the north-east of Shirley) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hospital estates such as Spire Southampton Hospital, 0.6 miles to the north of Shirley, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Construction mastic in Shirley, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. We work on internal decorators’ caulk, floor and skirting junctions and cladding and panel joints, and the failures we’re asked to look at most are missed perimeter joints on a new elevation and old sealant on a refurbishment that needs stripping before new work. Facilities teams, main contractors and managing agents in Shirley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Building work in places the size of Shirley is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
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.

Cost factors for mastic packages
These are the things that shape the price:
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Distance, for remote addresses
- How much there is to seal
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- The product your specification calls for
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Looking after the joints
After handover, a little attention goes a long way:
- Use the product the specification names
- Brief following trades on areas that have been sealed
- Don’t force external sealing on a damp or frosty day
- Ask for joint and product checks before the package is urgent
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault.
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, so the installer needs to correct it first. We raise them during our first walk of the area.
From enquiry to sign-off
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. Then we strip out anything that has failed, prepare every joint and seal it. What matters most for a job in Shirley is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site
- Make sure the joints can be reached
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Common problems we fix in Shirley
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge. Better to raise it at the start than seal a joint that’s bound to fail.
Things that typically lead to an enquiry:
- Window and door perimeters that won’t pass inspection
- Caulk cracking where joints are moving more than expected
- Frame gaps too wide for sealant alone
- Sanitary sealant damaged by following trades
Work at a hotel such as Elizabeth House Hotel, 1.3 miles east of Shirley, tends to be programmed around bookings, mastic included.
Questions to ask before you book
- Their public liability cover
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference. Where an alternative is genuinely suitable, we’ll say so. For buildings in places like Shirley, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Common questions from Shirley clients
Is Shirley too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is Liners Industrial Estate, near Shirley, within your area?
Yes. We cover Shirley and the area around it, including industrial estates, business parks and retail parks such as Liners Industrial Estate. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you take on mastic snagging only?
Yes. Share the list and photos, and a fixed quote follows, with the work timed to your handover date.
Can you seal external joints in wet or cold weather?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. Public liability insurance is in place.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
