At the annual awards dinner, held at the Royal Armouries in Leeds, WGL Stoneclean had an outstanding evening being shortlisted for its work under “Heritage” for Tower Works Leeds and also “Value” for Dean Clough A&B mills Halifax.

We are extremely proud to announce that we won the “Highly Commended” award for the value on Dean Clough A&B Mills, Halifax.

WGL Stoneclean Ltd was the smallest company there and was competing with the some of the biggest firms in the construction business, this just goes to show that our work and knowledge is getting noticed

We at WGL Stoneclean have been keeping an eye on technology and have invested and are training one of our operatives up to fly our drone in built up areas.

The benefits of this technology are endless, the most obvious use is to reach difficult to see area’s on a building where in the past you may of needed to hire a cherrypickers or scaffolding. When you do this you are also at the mercy on when it can be done and how much you have to spend.

Our first “Stately” Home

stately-home[1]

This 18th Century Hall in South Derbyshire is now in private hands. The first part of our contract was to clean the stonework of three elevations to remove the atmospheric staining of the last two hundred years. Our Steamacc Process applied from Access Platforms and our own scaffolding has revealed the startling colours of the original stone. We will be returning towards the end of the summer to repoint and repair the cleaned stonework.

Our largest ever contract

In February 2015, we commenced work on our largest ever contract, worth over £150 K, on the A and B Mills of the Dean Clough complex in Halifax. (picture attached). Once the largest industrial complex in the World, the Dean Clough site has been redeveloped by the Hall family over the last 20 years. The final part of the transformation of the complex the A and B Mills was entrusted to J F Finnegan Ltd of Sheffield at the start of 2015. In turn, we we contracted to undertake the internal blasting of internal walls and staircases to remove over 150 years of paints layers as well as cleaning the stonework of the external elevations with our Steamacc Process. On the conclusion of cleaning works we will also undertake extensive re-pointing of the stonework and a large number of masonry repairs. we expect to complete our works towards the end of the year.

The Arcade Royale, Halifax

In the second half of 2014 we were asked by the building managers to take on the project management of the Refurbishment of the Arcade Royale in the centre of Halifax. The new owners of the lower half of the Grade II listed building had recently let the building to new tenants and were keen to bring the structure back to a sound state after many years of neglect. The external elevations of the building were clad with a white “Marmo” tile developed in the early years of the twentieth century by Leeds Fireclay Company. The white tiles simulated a more expensive marble cladding and are found on buildings all over Northern England. We were contracted to manage scaffolding, cleaning and restoration of the stonework, roof repairs, external painting, internal timber preservation as well as some joinery and internal plastering repairs.

As ever our first step was to erect a scaffold on the Southgate Elevation and clean the tiles. We developed a modified cleaning procedure that involved a mild masonry detergent washed off with super-heated steam followed by a light acidic “wipe”. The cleaning result was a spectacular improvement in the tiles’ appearance to the considerable relief and approval of Calderdale Council’s Conservation Officers. However the cleaning revealed significant water damage to the tiles from failed gullies and leadwork on the roof. Roof tiles were replaced and the gullies cleaned, the leadwork replaced and coated with bitumen. We then secured the Marmo tiles which were in danger of detaching themselves from the structure with over 200 Helifix Terracotta stainless steel ties. We then undertook extensive colour matched tile repairs and repointing. Two internal offices which had suffered from water ingress were repaired, re-plastered and re-decorated. In early 2015 we will start work on the King Edward Street elevations of the building.

The North’s First “Consolidated” Building

What Does Railway Street Huddersfield have in Common with Easter Island, The Statue of Christ outside of Rio de Janeiro or Babylonian Tablets from 600 B.C.?

Early in 2014, we were asked by one of our regular customers, Nu Construction Ltd of Elland to quote for the cleaning and restoration of 6/8 Railway Street, Huddersfield. The building was derelict and had stood empty for nearly thirty years. It had suffered a major fire and other parts of the external paintwork had been painted with a covering that did not allow the building to “breathe”. As a result many of the sandstone features were crumbling back to sand.

In order to properly assess the damage that had been caused to the building over many years we first cleaned the stonework with a light, pressure regulated abrasive blast method using a Calcium Silicate stone grit to remove the paint and in other areas removed many years of carbon staining from atmospheric pollution with our “Steamacc Process” comprising a mild acid spray washed off with super-heated steam. The cleaning process revealed that many of the original stone features window, heads cills, string courses were in very poor shape and would require extensive repair and replacement.

As the ultimate client for the building was already confronting significant cost over-runs in other areas of the refurbishment he asked us to come up with an alternative strategy. The deposition of Silicon Oxide into the crumbling stone structure via a Silicic Acid medium had been developed in Europe and used extensively across the world, including the structures quoted in the first line. As a consolidation process would save an estimated £60,000 in stone repairs it was decided that we should proceed.

All very loose stone was carefully removed by hand. The stonework was then flood sprayed with the Silicic Acid on two occasions, separated by four weeks. As a final piece of insurance the consolidated stonework was treated with a silicone based water repellent. The stone work has regained much of its original strength and is now set for a life of at least 10 years allowing the client to carry out a programme of stone repair and replacement at his leisure.

City Walk, Leeds – Denmark to the Rescue!

In December 2013 we were contacted by Triton Construction Ltd who were in the process of re-furbishing City walk in Leeds – a relatively new office block – that required updating to the demands of the modern property market.

The building is identified by nine stainless steel clad columns on the front elevation. Over time these columns had become discoloured by some ugly brown stains that completely ruined the first visual impression of the building to existing and intending tenants.

We tried several “traditional” chemical remedies, including a strong masonry detergent and a mild alkali that produced an improvement but not a complete solution. Finally, via some contacts amongst our friends in the stainless steel fabrication industry, we discovered a Danish chemical that has been successfully used in the cleaning of stainless steel urinals. The very satisfactory results are shown below. Our reputation of “problem solvers” remaining happily intact.

The Building The Council Did Not Want Cleaned.

Penn House is a Grade II listed building that has stood on the corner of Bootham and St Marys in York for nearly 200 years. In 2013, the owner of Penn House, David Coidan formally requested planning permission to clean and repair the building. He mad his application on the knowledge that WGL Stoneclean had successfully cleaned and restored 51 Bootham in 2009 and had been awarded the York design award for listed buildings in 2010. 51 Bootham is about 70 metres from Penn House. Mr Coidan was therefore stupefied when planning permission was refused! Mr Coidan eschewed his right to appeal to York Council and with our assistance made an appeal directly to the Secretary of State, who promptly gave him permission.

We commenced work in March 2014 and completed the works in May. The brickwork was cleaned with our Steamacc Process – a mild acid spray with a super-heated steam wash off that was verified by the University of Leeds, Department of Civil Engineering as causing minimal damage to masonry. We also patch pointed the elevations, replaced some bricks, filled in holes and stabilised some cracks. The stunning results are shown below. In place of a black monolith standing testament to 200 years of Industrial airborne pollution, there is a stunning building built with hand made yellow bricks streaked with metal salts giving the bricks orange and brown colourations.

So far we have not received one complaint from a York resident at the ruination of one of their “dark, satanic mills”.

 

Deep clean uncovers Penn House’s original glory.

Using our diluted acid and super heated steam cleaning techniques, we have undertaken the considerable task of cleaning decades worth of soot, dirt and grime from the external brickwork at Penn House – one of the grandest and most historic buildings in York.

Pictures coming soon.
