Work on the property you already own. We scope it, put it out to competitive bid, coordinate the trades, and supervise the job through completion — with licensed and insured crews doing the work and one point of contact for you.
Exterior work on the home you own — roofing, siding, paint, decks, fences, landscaping and more. Plus full fix & flip renovations, inside and out, scoped and underwritten to a resale number.
See residential → Owners & asset managersTenant improvements, envelope and roofing, parking and site work, common areas, and make-ready between tenants — on the buildings you already hold.
See commercial →Tantum is not the crew on your roof. We write the scope, run it out to qualified contractors, compare what comes back on equal terms, and then supervise the work against the scope you approved. That structure is the whole point — the person checking the work is not the person invoicing for it.
We look at the property with you, agree on what's actually being done, and put it in writing — line by line, so nothing is left to interpretation later.
The scope goes to qualified contractors. We verify license and insurance, level the bids against the same work, and bring you a recommendation with the numbers.
Schedule, materials, sequencing, and site checks. Change orders come to you in writing with a reason and a price before anyone proceeds.
Punch list, final walkthrough, warranty documentation, and lien releases — so the job is finished on paper as well as on site.
For homeowners who want the exterior handled properly and once — whether that's a single roof replacement or a full refresh of the outside of the house before you list it, host, or simply stop worrying about it.
Take one, or bundle several into a single scope and a single schedule.
On a flip we do more than swing hammers. Tantum Realty Group can find the property, we build the scope of work, put the bid together, underwrite the deal against a resale number, and then run the renovation. One team from the acquisition through the day it goes back on the market.
Tenant improvements, envelope and roofing, site and parking work, and the refreshes that keep a property leasable. Scoped, bid, and supervised the same way — with reporting an owner or an asset manager can actually use.
