Commercial sealant contractors in North Ascot
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on external facade joints, movement joints in walls and floors and window and door perimeters, and the failures we’re asked to look at most are water staining near frames, panels or ceilings and window and door perimeter joints that have cracked open. For commercial sealant work in North Ascot, you deal with one contact from quote to sign-off, whether it’s one building or several.
Occupied buildings in North Ascot need the work phased: washrooms in turn, floors in sections and entrances kept open.
In a smaller place such as North Ascot, commercial buildings are normally a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Water from a services leak rather than a joint
- Walls or slabs moving more than any sealant can take
- Roof leaks that only look like a joint problem
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Your questions answered
Does a hotel in North Ascot need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is a smaller place like North Ascot 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. Where we can, we group nearby jobs to make the most of each trip.
How do you keep disruption to occupiers down?
Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing for as long as the cure needs.
Is the old sealant taken out first?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.
Do you work for facilities managers and managing agents?
Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.
Which site documents can you send us?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.

What else we do in North Ascot
What the job involves on each surface
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.
Why act early in North Ascot
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We’ll suggest an order, worst sealant joints first. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
A quote for sealant joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Signs you need commercial sealant contractors in North Ascot
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
Common reasons buildings call us in:
- Hardened, chalky sealant on south-facing or exposed elevations
- Frame sealant that has cracked, shrunk or pulled away
- Water staining near frames, panels or ceilings
- Gaps behind commercial kitchen worktops and sinks
For premises near Ascot station (1 mile south-east of North Ascot), footfall is part of the plan: work is phased so shops and offices keep trading.
