Apartment Renovation Contract: What to Check Before Signing

A renovation contract ties estimate, timeline, money, and liability. Clients read the price table but skip appendices: “not included,” change-order rules, MEP warranty, penalties, and final payment before defect fixes.

Profmaster has delivered turnkey apartment renovation in Moscow and the region since 2006. Below: what to verify before signing — scope, estimate, payment, change orders, warranty, acts, and traps. Reading estimate lines — in estimate guide; choosing contractor — in criteria article.

In short: read contract and estimate together. Early conflict between them usually resolves in favor of contract wording in dispute.

Why contract if you have an estimate

Estimate answers “what and how much.” Contract answers:

• when and in what sequence;
• how to pay and what counts as done;
• what happens with change orders and delays;
• what warranty and how to accept;
• who is responsible for materials, idle time, site access.

Without contract, estimate is a quote. Without estimate appendix, contract is marketing.

Pre-survey benchmark — capital renovation calculator. Final terms only in signed package after inspection.

If you simplify: estimate is shopping list, contract is rules of the game.

Contract structure: required sections

Section	Content	Risk if empty
Parties	Client, contractor (sole prop/LLC), details	No one to claim against
Subject	Address, work type	“What was promised” disputes
Estimate (appendix)	Lines, prices, total	No scope
Timeline	Start, stages, completion	Endless build
Payment	Schedule, advance, final	Overpay without acceptance
Materials	Who buys, equivalents	Defect and idle fights
Change orders	Approval process	Uncontrolled extras
Acceptance	Acts, defect window	No project close
Warranty	Term, scope, contact	“Not our area”
Liability	Delays, neighbor damage	No leverage
Termination	Exit terms	Stuck halfway

Verify appendix numbers: estimate, plan, material spec, sample act — all listed and signed.

Estimate in contract: how to cross-check

Algorithm with estimate reading article:

1. Contract total = estimate total (VAT treatment consistent).
2. Sections cover promised scope (demolition, MEP, rough, finish).
3. Exclusions in contract do not silently cancel estimate lines — find conflicts.
4. Estimate validity and material price revision rules.
5. Contingency — who spends and how documented.

Estimate element	Contract question
MEP	Not excluded in notes
Debris haul	In estimate / contract says excluded
10% contingency	Spend rules described
“Bathroom set”	Bill of quantities in appendix
Client-supplied materials	Delivery dates and idle

If contractor says “estimate is preliminary, exact on site” — fix deviation threshold and mandatory addendum before continuing if exceeded.

Payment schedule: safer pattern

Healthy logic: money follows accepted work.

Stage	Share (benchmark)	Condition
Advance / start	Small % or first-stage materials	After signing, before demolition
Demolition, rough	Per act	Screed, plaster, routing accepted
MEP	Concealed-work act	Photos, tests
Finish	By zone or room	Kitchen, bath, living
Final	Balance	After acceptance act and defect list

Payment red flags:

• 50%+ “for purchase” without breakdown;
• calendar payment without acceptance;
• final payment before defect fixes;
• no retention for warranty period if appropriate.

Retention is optional but useful on large budgets: small % until minor defect window ends.

Change orders and scope changes

Typical contract formula:

1. Discovery documented (act, photo).
2. Approval of price and time before start.
3. Addendum or supplemental estimate.
4. Acceptance as separate stage.

Situation	How contract should handle
Weak screed after demolition	Contingency or optional line
Riser replacement	UO vs contractor boundary
Client moves outlets	Addendum
Non-standard tile	Separate rate before install
Material price rise	Index formula or fixation

Verbal “we will do it and write later” breeds conflict. Demand written fix in correspondence at minimum.

Warranty: what to verify

Warranty is not abstract “two years on everything.” Reasonable split:

Work type	Warranty focus
Finish	Cracks, delamination in normal use
Waterproofing	Leaks in treated zone
Plumbing	Contractor-installed joints
Electrical	Connections, panel, installed devices
Third-party materials	Often manufacturer warranty

Clarify:

• term and contact;
• response and fix timeline;
• what is not covered (vandalism, neighbor flood, consumables);
• warranty void if client alters work.

Handover with defects — apartment acceptance checklist.

Acts: concealed work and final acceptance

Document chain:

1. Concealed-work act — before finish covers MEP/screed/waterproofing.
2. Stage acts — per payment milestones.
3. Final acceptance — defect list.
4. Handover — MEP diagrams, equipment docs if applicable.

Act	When	Attach
Concealed	Before tile/plaster over	Photos, diagrams
Stage	After rough/finish zone	Scope from estimate
Final	Before last payment	Punch list

Contract should set deadlines to sign acts and fix defects. Silence sometimes counts as acceptance — check wording.

Timeline, idle time, force majeure

Item	Why
Start and end dates	Project frame
Staged schedule	Payment tie-in
Client-caused idle	Material delay, access
Contractor-caused idle	Liability
Force majeure	Limits for both

Reality-check timeline vs scope: full gut “in one month” with full MEP — verify staged schedule.

Materials: who buys and who answers for defects

The materials block must be unambiguous — otherwise “who caused the tile crack” never ends.

Model	What to state	Risk if vague
Contractor buys all	Brands, equivalents, delivery to site	Silent class downgrade
Client supplies finish	List, volume, delivery date, idle rules	Crew idle, change order
Mixed	Rough by contractor, light and furniture by client	“Forgotten” mounts and rough-ins
Leftover materials	Who keeps them, in price or not	Handover disputes

Check material acceptance wording: who signs, hidden defect in packaging, batch replacement. For bath and kitchen cross-check bathroom checklist and kitchen estimate — client-supplied lines often hang there.

Sole proprietor, LLC, and who signs

Moscow contracts use sole prop, LLC, rarely individuals without status. Minimum checks:

• payment details match who you pay;
• signatory has authority — ask for power of attorney or charter excerpt if unsure;
• subject tied to specific address, not vague “client premises”;
• appendices have no blank sheets “to sign on site.”

Form	Client upside	Watch for
LLC	Clear structure, appendices	Wrong INN on invoice
Sole prop	Common in renovation	IP matches who runs site
Individual without status	None	No warranty or tax transparency

Contract does not replace contractor selection — it records the outcome. If manager promises orally what text lacks, get addendum before advance.

Liability and insurance

Clarify:

• who answers for neighbor flood during contractor work;
• insurance or deposit if required;
• access: keys, passes, building rules;
• material storage on site.

Moscow and region building rules differ — fix who orders passes and elevator protection.

Wording traps

Phrase	Risk
“As agreed by parties” without deadline	Endless approval
“Equivalent materials” without criteria	Class downgrade
“Visually acceptable”	Subjective acceptance
“Not included unless in estimate”	Hidden extras
“Client provides everything”	Logistics shifted to you
Contractor unilateral termination	Stop without your remedy

Summary

Renovation contract is client insurance: it turns estimate into obligations and sets rules for money, time, and warranty. Before signing, match appendices, payment schedule, change orders, and exclusions — together with estimate reading guide. A clear contract does not harm good contractor relations; it removes disputes where memory and expectations diverge.

Do not sign on trust what you would not review in an evening with calculator and checklist — that evening costs less than a month of rework.
