    Harford Specialised Services Ltd was formed in 1989 and is a remedial treatment company specialising in the eradication of rising damp, wood worm, insect infestation and fungal decay. In addition to these works we also carry out wall tie replacement works.

    Harfords is an approved contractor for many of the major manufacturers and we are used on a regular basis by many local surveyors, local authorities, agents and estate agents to carry out inspections on properties in Portsmouth and the surrounding areas.

    All treatments carried out by Harfords requiring chemical application use the most up to date, effective and environmentally friendly products.

    A big thank you to Harfords for the first class service we received from start to finish! We are very pleased with the end result and the work carried out to an excellent standard.
    Wouldn’t hesitate to use again, highly recommend.

    Can’t recommend this family run company enough, the specialists were fantastic from start to finish.
    James put my mind at rest on the first visit with his honesty, knowledge and suggestions.
    Grace in the office was a joy to deal with and so, so helpful.
    The specialists who attended and completed the work (Kevin & Cal), were so professional, tidy, respectful and helpful. I was more than happy to allow them access to my property in my absence.
    However I would say the boys do prefer Chocolate covered Hobnobs and not Luxury Chocolate Chip Cookies…I was a little disappointed about this, having not known this beforehand, as I felt compelled to eat the rest and now have to work them off 😉 !
    I would highly recommend using this company.
    Thank you Harfords

    Unknown, Southsea. (May 2019)

    Relocating from London and finding a builder before we moved was daunting. We were recommended Harfords and we have to say they have been FANTASTIC. We had quite a bit of work completed over the week. Mark has been with us all week and is just brilliant along with Barry, Tony with his team & the boss James. The team are friendly, extremely hard working and so very tidy too. We cannot recommend them highly enough. THANK YOU

    Simone & Paul, Southsea (August 2019)

    Mr & Mrs J Bartlett, Rowlands Castle (December 2019)

    Five years ago, I bought a house that needed a damp course and wall ties and Harfords did the work for me. I was so impressed with the first class service I received from Grace in the office, to James doing the quote and the standard of the work, I did not hesitate to contact them again earlier this year when I bought another house as I knew I would be in ‘safe hands’. I was nervous about the new purchase as the survey had shown some issues but James allayed my fears with his knowledge and honesty. The guys that did the work were friendly, professional and tidy and I am happy with the end result and would highly recommend this company on the quality of their work, the price and their first-class customer service (Damp proofing)

    S Kennedy, Fratton (January 2020)

    “Harfords were efficient, friendly and professional. The job which was replacing wall ties and repointing a first-floor rear wall was messy and time consuming but all of the team were polite, turned up on time, took time to explain the work and tidied up on the completion of the job. I would have no hesitation recommending them to anyone.”

    Mr & Mrs Griffiths, Southsea (June 2021)

    I am writing to tell you about the excellent service I received from Harford on a number of building projects that Harfords provided following the purchase of my nephew’s first home.

    From the free survey and written report to the final completion of the work. All aspects of your work and service have been first rate. Punctuality, reliability, quality and communication have been first rate. Customer engagement has been very impressive. I would have no hesitation to recommending you in the Portsmouth area and I will be using your services again.”

    Mr Stevens, Hayling Island (July 2023)

    “We used Harfords many years ago for something else and so they were our first choice of contractor for some damp we discovered. Because the house was unoccupied, James and his team were able to get in very quickly as they worked around their other jobs. They worked efficiently, giving us photo updates, and we were so pleased with how quicky they dealt with the problem. They then recommended and brought in another tradesperson, who was also very good. We are so pleased with the timescale and finished work and would have no hesitation in recommending them.”

    Would you pass on my thanks to the team for doing their utmost to complete the works to my exact specifications.

    The end results, particularly on the porch and fireplace have exceeded my expectations and I would be happy to recommend the company to anyone needing building work carried out.”

    S Long (November 2023)

    “Very pleased with the whole service from start to finish.  Surveyor turned up quickly and took the time to explain what his proposal was, and different alternatives.

    Team to carry out the work came promptly at agreed time and did a great job. 

    One minor hitch when putting radiator back was dealt with swiftly.

    Really good to see such good service today.  Tea and choc biscuits help as well.”
