Construction mastic in Earlsfield
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team before sealing starts.
How we handle construction mastic in Earlsfield
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Earlsfield, send drawings and the specification through our quote form. We work on internal decorators’ caulk, cladding and panel joints and floor and skirting junctions, and what we’re called in for most is sealant knocked or painted over by other trades and caulk cracking where joints are moving more than expected. For commercial sealant work in Earlsfield, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Construction in a London area such as Earlsfield means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Facades, frames and programmes in Earlsfield
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Earlsfield. Delivery slots and scarce storage shape how and when the mastic goes in. A good number of hotels sit less than 2 miles from Earlsfield. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When a college such as South Thames College Wandsworth Campus, 0.9 miles to the north of Earlsfield, builds or refurbishes, the mastic package typically has to fit around students and staff. Units on estates such as Rufus Business Centre (under half a mile south-west of Earlsfield) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Work at a hotel such as The Alma Hotel (to the north of Earlsfield) tends to be programmed around bookings, mastic included.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions we are asked in Earlsfield
Does your area include sites such as Rufus Business Centre, near Earlsfield?
Yes. We cover Earlsfield and the area around it, including industrial estates, business parks and retail parks such as Rufus Business Centre. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you stick to the specified products?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. If the frame is life-expired, we’ll tell you. Failed sealant in a building in Earlsfield can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Commercial clients in Earlsfield
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two on a small fit-out and several weeks on a large multi-storey package, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
- Let building users know which areas are affected

Advice
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Joint design decisions that belong to the architect or engineer
- Glazing units that are cracked or misted
- Rework caused by others damaging completed areas
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
