Questions about St Mary's
Our building in St Mary's is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is St Mary's too far out for you?
Not at all. St Mary's is within our area. 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.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What do you charge?
Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or send details through our quote form with a description of the work.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
About our facade sealing in St Mary's
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve hard, chalky sealant that no longer flexes and discoloured or dirty facade joints, across shopfront frames, stone and brick facade joints and coping and flashing joints. Facilities teams, main contractors and managing agents in St Mary's tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
On a small site around St Mary's, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

New build and refits around St Mary's
St Mary's is within about 1 mile of the coast. 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. A good number of hotels sit less than 2 miles from St Mary's. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
New units and refits on sites such as Central Trading Estate (under half a mile south-east of St Mary's) need their panel and perimeter joints sealed to the specification. Hotels like Leonardo Hotel Southampton, under half a mile to the north-west of St Mary's, rarely close for long, so refurbishment mastic is phased floor by floor. Further education sites such as Southampton City College, under half a mile south-east of St Mary's, are extended and refurbished from time to time, with mastic often programmed into the summer break.
St Mary's is about 1 mile south of Southampton, in Southampton. Looking for facade sealing in St Mary's? We can help, as we do across Southampton. St Mary's is one of 30 places we cover in Southampton.

We also cover Northam (1 mile north-east), Inner Avenue (1 mile north), Peartree Green (1 mile east), Southampton (1 mile north) and Bitterne Manor (1 mile north-east). Bigger towns within reach include Harefield (3 miles east), Maybush (3 miles north-west), Coxford (3 miles north-west), Lordswood (3 miles north-west), Mansbridge (3 miles north-east) and Redbridge (3 miles west).

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Quoting for work in St Mary's
We price every job individually. The main factors are:
- Working within restricted access windows
- Joint width, depth and condition
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
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.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email us.
Why it’s worth doing now in St Mary's
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Small buildings around St Mary's suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
