When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Specifying the product where the designer hasn’t
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Cladding and panel joints
- Window and door perimeters
- Floor and skirting junctions
How we handle construction mastic in Drayton
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on window and door perimeters, internal decorators’ caulk and floor and skirting junctions, and the failures we’re asked to look at most are different trades sealing to different standards and perimeter gaps outside the sealant’s range. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Drayton, preparation and product choice get the time they need.
On a small site around Drayton, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Construction mastic around Drayton: what changes locally
The sea is no more than about 1 mile from Drayton. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Drayton 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.
Projects at colleges like Portsmouth College, 2.5 miles to the south of Drayton, tend to run to term dates, so the mastic is planned tightly. When units on a site such as Railway Triangle Industrial Estate, 0.6 miles to the south-west of Drayton, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. New wings at hospitals like Queen Alexandra Hospital, 1.2 miles to the west of Drayton, bring long runs of window and panel joints to seal.
Drayton is about 2 miles south of Purbrook, in Portsmouth. Across the PO6 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Drayton is one of 19 places in Portsmouth on our list for mastic packages.

Leave it or put it right?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. Snagging can be priced as a separate stage. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Questions about Drayton
Is a smaller place like Drayton outside your area?
No. Places such as Drayton are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like Queen Alexandra Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Different surfaces, different methods
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and reduces snags.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near Drayton can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
