What we are called out for in Staines Green
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.
Site and facilities staff are often the first to spot these:
- Facade joints cracked through the middle
- Failed seals around shopfront and entrance frames
- New sealant peeling off old mastic
- Unsightly perimeter sealant on a visible elevation
Building work at universities like University of Hertfordshire, 3 miles south-west of Staines Green, is often timed for the summer, mastic included.

Facade sealing for commercial buildings in Staines Green
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and what we are called in for most is hard, chalky sealant that no longer flexes and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Staines Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In the countryside around places like Staines Green, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

- Joints whose design needs changing by the specifier

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Staines Green are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Point out parking and an unloading spot
- Share the asbestos register for older buildings

Questions about Staines Green
Can you take on a job at a hospital such as Hertford County Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Staines Green outside your area?
Not at all: smaller places are covered as well as 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.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you replace failed glazing units?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.

Leave it or put it right?
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Converted and older buildings near places like Staines Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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.
