Home Restoration Specialists

Your Home Restoration Specialists for architectural preservation was started in California in 2007 but has over 38 years experience between New York City and Los Angeles. Projects in Manhattan included several of the Dakota Row Houses on West 73rd Street, many Central Park West Art Deco buildings, and an Upper East Side 1864 brownstone restoration which was owned by a well-known  Pulitzer Prize-winning writer.

Projects in Los Angeles included many houses in Whitley Heights (the original movie colony in Hollywood), Silverlake, Hancock Park, Larchmont Village, Echo Park, Los Feliz, Coldwater Canyon, Lafayette Park, Westwood, and Eagle Rock, as well as other areas. 

We were fortunate to have had the opportunity to work on the Bolton House in Pasadena, designed by the Craftsman architects Greene and Greene - built in 1906, and placed on the National Register of Historic Places. Projects included restoration of all seven bathrooms, the entire dismantling and full restoration of another room, replication of the original garden pergola, wood and plaster restoration, foundation re-pointing, discovering and restoring original pathways, including many landscape elements, consultation, and the implementation of countless suggestions.

The Home Restoration Specialists finished another project that was from the Pasadena Department of Water and Power in restoring the entire exterior of the historic 1930 Wilson Booster Station - a pumping station in McDonald Park and located in the Bungalow Heaven Historic District. The building was the only remaining structure of the original plan of the reservoir and park that was located on the entire square block site.  

And in Glendale, a wonderful 1914 Craftsman home required the replacement of over 750 cedar barn shingles, a somewhat detail oriented and difficult task, as they are lined up in a geometric pattern and are not randomly placed.

Please don't hesitate to call your Home Restoration Specialists for our architectural restoration services -  including vintage tile work and vintage plumbing.   


  1. “Renaissance Man Restoration either personally does the highest quality work himself, or supervises an entire project with his long list of trustworthy and equally qualified subcontractors to ensure that all proceeds in a logical and effective manner." Richard - Santa Monica
  2. "He is a general contractor who is extremely knowledable with any type or style of architecture. and has a wonderful source of licensed subcontractors who are qualified to do any project that is presented. He also supervises everything on the job, to ensure the best possible result". 5 stars. Pat - Hancock Park.
  3. “I owned two Craftsman Bungalows in Pasadena which I was able to sell only through the efforts of John, both in the actual restoration and with his good relations with the building department and background in landmarking and creating special districts. I also have a duplex in Venice Beach which has been totally restored on the exterior, and along with the colors chosen has made it a showcase. A very talented and trustworthy individual. You couldn't ask for anything more.” Larry - Venice Beach
  4. "An extensive knowledge of various architectural styles as well as preservation and restoration is quite impressive -with attention to the smallest detail resulting in a wonderful final product, including faithful replications of architectural details. He has an architectural background and corrected my architect's plans, making several blueprint revisions in design and terminology which enabled him to get all plans approved and permits obtained from the City of Pasadena that were rejected in previous attempts by others. Superior quality work at very reasonable prices. Most highly recommended." Thomas - Pasadena
  5. "I knew John from a previous consultation and when I bought this 1925 California Bungalow I asked him if he would take on the task of doing a faithful and complete historic restoration, combined with a total upgrade of the building. Most would have considered it to be a 'tear down' but I was elated when John accepted the challenge. The end result has transformed this beautiful little house into what it was when it was built - and that much more. His unique design capabilities and choices of colors are simply wonderful - and his attention to the smallest detail is extraordinary. He had full control over the project and even found vintage lighting and the original telephone! No one else would have understood this project or how to proceed with it. Everyone said we were both crazy but John did yet another miracle. And I thank him for it". Steven - Pasadena
  6. "Our wonderful historic house was built by an Italian immigrant cellist who loved rocks. Silvio Lavateili played with Leopold Stokowski, was part of the Woodstock Art Colony and 'Maverick String Quartet Concerts', had an afternoon radio program, and appeared in 'Swiss Miss' and 'Saps at Sea' with Laurel and Hardy. His beloved house has suffered over the years and John took on the task of faithfully restoring the exterior to its original condition -uncovering forgotten concrete ramps, making beautiful stairs and pathways with all custom railings, and replacing most of the original siding and trim. Our wonderful house finally looks as it should be and it's absolutely incredible! Silvio would be proud and would also be very much appreciative - as we are". Louis and Kumari - Eagle Rock.
  7. "Last week we were delighted to see Mr. Diele's work on the total exterior restoration of the 1930 historic Water Pump Station at McDonald Park" - "Maintenance of historic structures involves not only the regular repair of worn and weathered elements but also has the additional requirement that the treatments be historically appropriate in technique and finish" - "The color palate that he has selected to refinish the exterior surfaces achieves this requirement" - "We extend our support of all of Mr. Diele's work" Pasadena Heritage
  8. "I have known john for 10 years and during that time his talents and exceptional services have been invaluable to me. All work that was done, including full and complete 'take-down' restorations, was undertaken in a properly scheduled and professional manner - with a faithful respect to the original design. Extremely trustworthy and dependable as well as being most personable,he would be an asset to any project. Tom - Pasadena
  9. "John was hired to do an full and extensive exterior restoration of our home. He repaired totally rotted rafter tails, replaced fascia, installed window trim where none existed, and custom aged everything to appear original. He is hands-on, whether he performs the work himself, or oversees the craftsmen he hires. My house has been entirely transformed back to how it was intended to be. The work was very reasonably priced for what he does. He is very highly recommended." John - South Pasadena
