Historic Home Renovation in New Jersey
New Jersey has an unusual density of significant older housing: Montclair Victorians, Glen Ridge center-hall colonials, Princeton federals, Ridgewood shingle-style homes, and Bergen County farmhouses that predate the towns around them. Renovating one well means respecting what the house is while making it work for how people live now.
Strong Construction LLC has 20 plus years of experience with historic properties across Northern and Central New Jersey. We handle preservation commission applications, sealed structural drawings, and the fine carpentry that makes new work disappear into old.
Preservation commission approvals prepared properly
Montclair, Glen Ridge, Princeton, and several Bergen County towns maintain historic preservation commissions that review exterior changes in designated districts. The applications that fail are the ones submitted with vague descriptions and stock product cut sheets. We submit measured existing-condition photographs, dimensioned elevations, window and door schedules with muntin profiles and sightlines, siding and trim specifications, and a written statement of how the proposal relates to the original architecture. We attend the hearing and answer questions so you are not defending your own project alone.
Matching original millwork and detail
Stock lumberyard trim never looks right on a house built in 1895. We template existing profiles, grind matching knives where necessary, and run replacement casing, base, crown, and porch detail in our own shop. Balusters, brackets, corbels, and coffered ceilings are reproduced from the surviving originals. Plaster is repaired as plaster. Where a modern element such as an appliance panel or a hidden door must exist, we detail it so the eye reads the original rhythm of the room rather than the intrusion.
Modern systems inside an old envelope
Comfort in a historic house comes from careful, unglamorous work: air sealing at the attic plane, dense-pack or mineral wool in the walls where it can be done without trapping moisture, storm windows or restored sash with proper weatherstripping instead of vinyl replacements, and right-sized HVAC using small-duct or ducted mini-split systems that fit in existing chases. We also address knob-and-tube remnants, undersized services, and the galvanized supply lines that quietly strangle water pressure.
Written pricing on unpredictable buildings
Historic work carries genuine unknowns, and we manage them with investigation rather than optimism. We open selective areas early, document what we find, and write allowances with real dollar figures. Kitchens in these homes typically run $45,000 to $85,000, with full-gut custom kitchens at $110,000 and up. Bathrooms run $20,000 to $40,000, with high-end primary baths $40,000 to $75,000. Exterior restoration, structural repair, and system replacement are priced separately so you can phase the project across seasons or budgets if you choose.
Where we work on historic homes
We renovate historic properties in Montclair, Glen Ridge, Bloomfield, Ridgewood, Tenafly, Englewood, Summit, Westfield, and Princeton, along with the row house districts of Hoboken and Jersey City. Each town runs its review differently. Montclair and Glen Ridge focus heavily on window replacement, siding, and porch alterations. Princeton reviews additions and streetscape impact closely. Ridgewood and Tenafly apply zoning coverage rules that shape what an addition can be before preservation is even discussed. We check all of that at the feasibility stage so the design we develop is one that can actually be approved and built.

Frequently Asked Questions
Do I need historic commission approval to renovate my kitchen?
Interior work almost never requires preservation review. Approval is generally required for exterior changes in a designated district, including windows, doors, siding, roofing, porches, and additions. We confirm your property's status with the town before design begins.
Can original windows be kept and still be efficient?
Usually yes. Restoring the sash, replacing failed glazing putty, adding proper weatherstripping, and installing interior or exterior storms typically performs close to a replacement unit while keeping the original glass and profiles that make the house look right.
Do you handle permits and inspections?
Yes. We pull the building, plumbing, electrical, and fire permits, coordinate the plan review with the local construction office, and meet every inspector on site. You never have to sit in a municipal office or chase a subcode official. Our license and insurance certificates are filed with the township before we start.
How long will the work take?
A kitchen typically runs eight to twelve weeks on site once materials are in hand, a bathroom four to six weeks, and a whole-home renovation four to eight months depending on structural work. We order cabinetry and stone before demolition so your home is not sitting open waiting on a delivery.
