Renovating a condominium or high-rise apartment in Houston is fundamentally different from renovating a single-family home — and most contractors are not equipped for the difference. Shared plumbing stacks. Concrete slab penetrations requiring engineering sign-off. Building management coordination. HOA approval processes. Noise and dust protocols that govern every trade on every day. Freight elevator scheduling. Neighbor impact management. Alquimia Inc. is one of the few Houston contractors who regularly manages renovation work inside the city’s luxury residential towers. We handle the complexity so you do not have to.
What Makes a High-Rise Renovation Technically Different
A high-rise renovation is not a single-family renovation with an elevator. The building systems, structural constraints, coordination requirements, and neighbor impact protocols create a project environment that requires specific experience — not general contracting experience applied to a new setting.
Concrete construction. Most Houston high-rises are concrete-framed structures. Penetrating a concrete slab for a drain relocation requires core drilling and, in many buildings, structural engineering review before any work proceeds. Alquimia knows where concrete can be penetrated and where it cannot, and we engage structural engineers when the scope requires it.
Shared building systems. Plumbing stacks, electrical risers, and HVAC infrastructure are shared between units in multi-family construction. A drain reconfiguration that works easily in a single-family home may be impossible in a high-rise where the drain must connect to a shared stack at a fixed location. Alquimia designs the renovation around the building’s actual infrastructure — not around an ideal we would prefer to build.
Building management and HOA. Every high-rise renovation in Houston requires coordination with building management and, typically, HOA approval for the scope of work. Insurance certificates, noise restrictions, work hour limitations, freight elevator scheduling, and protection of common areas all require advance coordination. Alquimia manages all of it — building management knows us, we know the process, and we do not put the client in the position of navigating building bureaucracy while also managing a renovation.
Neighbor impact. Renovation work in a multi-family building affects neighbors in ways that do not exist in single-family construction. Dust, noise, and vibration are managed through protocols specific to each building. We communicate with affected neighbors before work begins, manage the impact throughout the project, and maintain the relationships that allow construction to proceed without building management intervention.
High-Rise Renovation at Every Scale
Full Gut Renovations
A full gut renovation takes the unit to the concrete and rebuilds it from the inside out — new layout, new plumbing configuration (where the building infrastructure allows), new electrical, new mechanical ventilation, new finishes throughout. This is the most complex scope in high-rise renovation and the one where contractor experience matters most. Alquimia manages full gut renovations in Houston’s most demanding residential buildings, coordinating structural engineers, building management, HOA approval, and the full sequence of trades from demolition through final finish.
Kitchen Renovations
A high-rise kitchen renovation involves the same building constraints as any high-rise scope: plumbing rough-in coordinated with the stack location, electrical adequate for the appliances selected, ventilation designed for the building’s specific infrastructure, and finish work that is architecturally consistent with the rest of the unit. Alquimia manages kitchen renovations in high-rise buildings with the same rigor we bring to full gut renovations — correctly specified, correctly sequenced, correctly executed.
Bathroom Renovations
Bathroom renovations are the most technically demanding scope in any high-rise unit: waterproofing systems that must perform correctly in a concrete building, drain configurations constrained by the shared stack, exhaust ventilation coordinated with building infrastructure, and floor penetrations that require building management awareness. Alquimia builds high-rise bathrooms with building science at the foundation — correct waterproofing before the first tile, ventilation sized to the space, substrate preparation appropriate to the finish selected.
Full Unit Refresh
For clients whose unit does not require a full gut renovation but needs significant updating — new flooring throughout, kitchen and bathroom surface updates, lighting, paint, and millwork — Alquimia manages the full scope as a coordinated project rather than a series of independent contractor engagements. The result is a unit that looks intentional and coherent throughout, not a collection of updates that do not relate to each other.
Houston’s Luxury Residential High-Rises
Alquimia has managed renovation work in Houston’s premier luxury residential towers across the Galleria, River Oaks, Midtown, Museum District, and Downtown corridors. We know the building management teams, we understand the protocols of different buildings, and we have the track record with HOA boards that allows projects to be approved and managed without friction.
If you are renovating in a building we have not worked in before, our process for establishing that relationship — insurance, work authorization, noise and hours protocols, elevator scheduling — is the same. We handle it before the first trade enters the building.
Why Building Science Matters Even in a High-Rise
High-rise buildings present specific building science challenges that single-family renovation does not. Stack effect — the pressure differential created by warm air rising through a tall building — drives air infiltration through unit walls and penetrations in ways that can bring humidity, odors, and air quality problems into the unit. Concrete construction creates thermal mass but also thermal bridges where concrete elements conduct heat through insulated assemblies.
Alquimia addresses building science in high-rise renovations where the scope allows: air sealing at penetrations and unit boundaries, mechanical ventilation designed for the unit’s actual ventilation needs, and moisture management in bathroom assemblies that is engineered to perform in the building’s specific conditions.
How a High-Rise Renovation with Alquimia Unfolds
Discovery and Building Assessment. Before scope development, we understand the building: its structural system, plumbing stack locations, electrical infrastructure, and the specific protocols of building management and the HOA. This assessment determines what is possible in the unit before any design decisions are made.
HOA and Building Management Coordination. We manage the HOA approval process, insurance certificate submission, and coordination with building management for work authorization, elevator scheduling, and noise and hours protocols. This phase runs concurrent with design and preconstruction.
Preconstruction. Permits where required. Trade scheduling coordinated with building elevator and freight access. Materials procured with lead time that does not compress the construction schedule. Structural engineering engaged where concrete penetrations or modifications are in scope.
Demolition and Discovery. High-rise demolition regularly reveals conditions that affect the scope: plumbing that does not match the drawings, electrical that was modified without permits, concrete conditions that change what can be relocated. We document what we find and brief the client before proceeding. Nothing proceeds without client knowledge and approval.
Construction. All work executed within building management’s approved hours and protocols. Neighbor communication active throughout. Building common areas protected at all times. Inspections completed at required phases before work is closed.
Finish and Completion. Finish work sequenced correctly. Punch list process that does not close until every item is resolved. Final walk-through with the client and, where required, building management inspection.
How High-Rise Renovation Pricing Works at Alquimia
High-rise renovation costs vary by scope, unit size, finish level, and the specific building’s infrastructure constraints. Alquimia works on a cost-plus basis exclusively — every dollar spent is documented at actual cost, and our fee is separate and explicit.
This matters in high-rise renovation because the building constraints that govern the project are not always fully known at the outset. A drain relocation that appears straightforward may require engineering review and concrete core drilling. In a cost-plus model, those conditions are addressed correctly and transparently. You see what they cost and why they are necessary.

Frequently Asked Questions
What buildings in Houston has Alquimia worked in?
We have managed renovation work in luxury residential high-rises across the Galleria, River Oaks, Midtown, Museum District, and Downtown corridors. If you are in a building we have not previously worked in, our process for establishing that relationship is the same — we handle insurance, work authorization, and building protocol before the first trade enters.
How does HOA approval work?
Most Houston high-rise buildings require HOA or building management approval for renovation scope, particularly for anything touching plumbing, electrical, or structural elements. Alquimia manages the approval process: scope documentation, insurance certificates, trade credentials, and the coordination required to get the project authorized before construction begins.
Can you move plumbing in a concrete high-rise?
Sometimes. Drain reconfiguration in a concrete building depends on where the shared stack is located and what the building management will authorize. Where reconfiguration is possible, it requires core drilling through the concrete slab — a process that requires engineering review in most buildings. Alquimia evaluates what is possible before any scope is committed to.
Do you handle the noise and scheduling coordination with neighbors?
Yes. Neighbor communication, noise protocol compliance, and the ongoing relationship management that keeps construction from generating building management complaints are part of how we manage every high-rise project. Clients should not have to field calls from building management about their contractor’s behavior.
How long does a high-rise renovation take?
A full gut renovation in a high-rise typically runs 3–6 months depending on size and scope, with building access constraints adding time compared to a single-family project. A targeted kitchen or bathroom renovation runs 6–10 weeks. We produce a detailed schedule at the preconstruction stage and manage to it within the building’s access protocols.
What is building science and why does it matter in a high-rise?
Building science in a high-rise context addresses stack effect (pressure-driven air infiltration through unit boundaries), mechanical ventilation for units that may be more sealed than single-family homes, and moisture management in bathroom assemblies. Alquimia addresses these conditions where the renovation scope allows — resulting in a unit that is more comfortable, healthier, and better sealed than it was before.
