How we handle facade sealing in Hempstead
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. The enquiries we see most involve water coming in around window frames and previous reseals run over old sealant, across cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure. One point of contact handles commercial sealant work in Hempstead from the first photographs to the final walk-round, for single jobs and planned programmes alike.
On a small site around Hempstead, 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.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Hempstead
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, saving a second set-up. For buildings in places like Hempstead, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What you get with us
- Products installed to the manufacturer’s instructions
- A Constructionline member, so easy to vet
- Colours confirmed for the specified product
- Clear, fixed quotes

Your questions answered
Can you work around term dates at a campus such as University for the Creative Arts - Rochester?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Hempstead too small for you to travel to?
No. Places such as Hempstead are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Our process
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 Hempstead, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
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. Getting these wrong usually costs more in the end than doing them right.
What else we do in Hempstead
Aftercare for building managers
Once the work is signed off, these steps help:
- Avoid harsh cleaners on facade sealant
- Check the asbestos register before old mastic is disturbed
- Keep the sealant details on the building file
- Avoid patch repairs on failed facade joints
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients 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.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Facade sealing in Hempstead: the local picture
Hempstead lies within about 3 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Hempstead included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
For a contractor working at a hospital such as Medway Maritime Hospital, which lies north-west of Hempstead, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Hempstead Valley Shopping Centre (0.6 miles south of Hempstead) brings panel joints and frame perimeters into the programme. When a school such as Hempstead Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.
Hempstead is about 2 miles south of Gillingham, in Medway. Across the ME7 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Medway, 54 places are covered, including Hempstead. For work in that direction, see our London page, about 30 miles away.
