Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Cracked or spalling substrates that need repair before sealing
- Work on the window or framing system itself
- Water getting in through cracked render or porous masonry
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

How we handle facade sealing in Upper Street
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. If you’re dealing with weathered joints at frame-to-structure perimeters and water coming in around window frames, we can help. Searching for sealant specialists in Upper Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Upper Street is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or send photos by email and we’ll arrange a return visit.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Upper Street can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.

Questions we’re asked in Upper Street
Is Upper Street off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can you work at a site such as Arch Farm Industrial Estate, by Upper Street?
Yes, sites like Arch Farm Industrial Estate are within our area, along with the rest of Upper Street. Photos and a short description are enough for a first look.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How do I request a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

How the quote is worked out
These are the things that shape the price:
- How much existing material needs removing
- Whether the work must be split into stages
- The size and state of each joint
- Location, for remote and island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Whether the building will be occupied during the work
- Access details, including height
- The postcode of the building
- Any dates the work must fit around

Facades, frames and programmes in Upper Street
Rainfall across the South East, Upper Street included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Projects at schools like Breamore Church of England Primary School work to term dates, so mastic is programmed tightly. New units and refits on sites such as Arch Farm Industrial Estate, 2 miles south of Upper Street, need their panel and perimeter joints sealed to the specification. On a healthcare site such as Fordingbridge Hospital, which lies south of Upper Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Upper Street is in Hampshire. Anywhere in SP6, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Upper Street is one of 723 places in Hampshire on our list for facade joints. Our Southampton page has more on work in that area, about 18 miles away.

In Upper Street, that means premises near Bat and Ball pub and The Burgate School and Sixth Form. Other landmarks nearby include Fordingbridge Museum (2.5 miles south) and Salisbury District Hospital (5.5 miles north).
Why act early in Upper Street
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Older rural buildings around Upper Street 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. For a fixed figure, call for a quote and we will price your job on its own details.
