Existing Floors

Existing Raised Access Floors, whether originally by Tate or by others will be expertly inspected and identified by our project managers in order to provide the most seamless addition or re-work. We often find floors with these common problems:

  • Delaminated finishes
  • Damaged trim edges
  • Deformation due to overloading

We can provide technicians to re-level existing floors, provide new or used panels to replace delaminated or damaged panels. We can install new ramps and steps, handrails, security cages, or any other associated equipment.

Our experienced installers provide equipment and cable cut-outs on site for custom equipment installations. Whether you have new equipment or are moving existing equipment, we can provide cutting, in-filling, trimming of cut panels, and stand installation.


With experienced, factory trained Union installers, many who have been working with us for over 20 years, Longden Company has successfully completed millions of square feet of critical spaces throughout New England.

Replacement PanelsRe-LevelingPanel CutoutsEquipment Cut-Ins

Are you looking for replacement panels for your existing raised access flooring system? Longden offers a replacement access floor panel program where we can assist you in properly identifying your existing raised access floor and in many cases provide you with both new and pre-owned replacement options, regardless of the age or manufacture of your access floor system.

Access flooring has been in existence since the 1960’s and has incurred many changes over the years, both in terms of manufacturers and models that have come and gone. Our staff includes individuals who have over 25 years experience in the access flooring industry. We have the ability to properly identify, match and provide you with a price for replacement panels and components to fit your existing floor system.

Refurbished / pre-owned access floor panels are a cost effective alternative to new access floor panels. Longden has a 16,000 CF warehouse stocked with both new and used access flooring material, from manufacturers like Tate, Donn, USG, ASM, CTec, Haworth, Liskey, Maxcess, and Floating Floors, to suit your access flooring material needs.

Do you have any issues with the integrity of your existing raised flooring system? Longden Company can correct potentially hazardous conditions that might exist within your data center/ server room environment. We can re-level your floor, to correct rocking panels and eliminate potential trip hazards.

Pedestals can come loose when old adhesive dries out, presenting the possibility of a floor collapse. We can check to make sure the pedestals are properly adhered to the base subfloor and re-glue them where needed. Missing stringers create a lack of lateral stability and integrity of the floor system. We can supply and install replacement parts where needed.

We also replace missing or broken tile edge trim to provide a more air tight floor as well as eliminating a path for dirt and debris to enter the subfloor environment.

Are you adding new equipment on top of your existing raised flooring system, thus requiring cutouts in the floor panels for the passage of new cables or wiring? Longden can assist you in cutting the openings in your existing floor panels, and installing cutout trim along the edge of the cutout opening to protect your wires.

L-molding is typically used in trimming of raised access floor panel cutouts. We can also provide un-trimmed cutouts for floor boxes or floor diffusers, should you be adding either of these components to your existing space. Additionally, we can furnish and install raised floor grommets.

Are you expanding upon your existing cooling or power systems in your data center/ server room, thus adding either new computer room air conditioning units (CRACU) or power distribution units (PDU)? Are these units being installed on stands within your data center/ server room?

Longden has assisted many facilities and IT personnel in installing the new stands into the existing raised access floor system. We can install and level the equipment stand, and cut-in the raised floor tight to the new stand, to ensure proper installation and maintain the safety and integrity of the floor.
