What We Do
Everything Under
One Contractor
One crew, one point of contact, from permit to punch list. No juggling subcontractors, no finger pointing when something goes wrong.
Kitchen Remodeling
A kitchen that fits how you actually cook and gather. Custom cabinetry, solid surfaces, and layouts that earn back every square foot.
Bathroom Renovation
Dated bathrooms rebuilt into rooms you look forward to using. Waterproofed properly, tiled cleanly, finished to last decades.
Flooring
Hardwood, tile, vinyl, and luxury plank installed flat, tight, and quiet. Prepped right so it still looks level in ten years.
Painting & Drywall
Walls that read smooth in raking light. Proper prep, clean lines, and no roller marks showing up a week later.
Roofing & Siding
The layer that protects everything else you own. Roofing systems and siding installed to shed water for good, not just to pass inspection.
Decks & Porches
Composite decks, covered porches, and outdoor living space built to code and built to hold a full house of guests.
Commercial Build-Outs
Retail and office space finished on a schedule that respects your opening date. Built around your brand, not a generic template.
Why 1JM
Built on Integrity,
Delivered with Excellence
Every project starts with listening. Your home is not a job site to us, it is where your life happens. So we bring precision, straight answers, and a clean site to every single day of the build.
We frame it ourselves
The structure is not subcontracted out. Our own crew does the framing, so what is behind the drywall is held to the same standard as what you see.
The price you approve is the price you pay
Itemized estimates with real numbers. If something changes, you hear it from us before the work happens, never on the final invoice.
You always know what is next
Regular updates and a named point of contact. No wondering whether anyone is showing up tomorrow.
We leave it clean
The site gets swept at the end of every day. You still live here while we work, and we build like we remember that.
Our Work
See the Difference
Real projects across Philadelphia and the surrounding counties. Same camera angle, before and after. Drag the handle to reveal the finished build.
Stone Carport Rebuild
An original stone structure carefully taken down and rebuilt with the existing masonry preserved, a new gable roof, and a poured slab. Old stone, new structure.
Two-Car Garage Addition
Framed from a bare slab to a finished structure with board and batten siding, a standing seam metal roof, and a loft window over the bays. Built to match the main house, not to look bolted on.
Covered Front Porch
A flat facade turned into a covered porch with a hip roof, wood ceiling, and composite decking. The kind of front step people actually sit on.
Full Home Addition
A two-story wing plus a covered porch, taken from excavation and ZIP System sheathing through to finished siding and roofing. The addition reads as original to the house.
New Composite Deck
Bare backyard to a full deck with composite boards, white posts, black metal railings, and wide steps down to the lawn. No annual staining required.

Questions
Before You Call
How much will my project cost?
It depends on scope, but you will never guess. After a free on-site visit we send an itemized estimate with real numbers, and that is the number you pay unless you approve a change in writing.
How long does a project take?
A bathroom runs a few weeks, a full addition runs a few months. You get a written timeline with your estimate, and we tell you early if anything shifts.
Are you licensed and insured?
Yes. Fully licensed and insured in Pennsylvania. We are glad to send the documentation before you sign anything.
Do you handle permits?
Yes. Permits, inspections, and code compliance are on us. It is part of the job, not an extra you chase.
Can I stay in my home during the work?
For most projects, yes. We contain the work area, protect what is not being touched, and clean the site daily.
What areas do you serve?
Philadelphia and the surrounding counties.
Do you offer free estimates?
Always. The consultation and the written estimate cost nothing and carry no obligation.
