Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Selsfield Common, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Arrange parking or a loading space
- Confirm the product named in the specification

How we handle construction mastic in Selsfield Common
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. If you have sanitary sealant damaged by following trades and frame perimeters left unsealed or poorly sealed, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Selsfield Common, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Selsfield Common bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Is a hospital such as Queen Victoria Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Selsfield Common off your patch?
No. Places such as Selsfield Common are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you work to our specification?
We follow the specified sealant, and we will raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do your applicators hold CSCS cards?
CHAS and Constructionline are both in place, and each applicator is CSCS-carded. We’re fully insured for public liability.
Does weather affect external mastic work?
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.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Frames fitted out of tolerance
- Glazing units that are cracked or misted
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.
What we seal
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
- Internal decorators’ caulk
After the work
After handover, these steps help:
- Keep scrapers and abrasive pads off new beads
- Check frame gaps are within the sealant’s range before sealing
- Brief following trades on areas that have been sealed
- Ask for joint and product checks before the package is urgent
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
New build and refits around Selsfield Common
Selsfield Common sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. A 2-mile radius around Selsfield Common takes in several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
For contractors refurbishing units at places like Rowfant Business Centre, which lies north-west of Selsfield Common, the mastic covers cladding panels, roller-door and window perimeters. School extensions, at buildings such as Turners Hill CofE Primary School, typically run to the summer holidays, mastic included. Historic houses such as Gravetye Manor (to the east of Selsfield Common) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. Older rural buildings around Selsfield Common move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
