Short answer
A contract must define scope, price, allowances, payment milestones, the change-order process, a schedule, warranty and what happens if either party stops. If any of those is absent, that is the one that will be disputed.
Allowances are the clause to read hardest. An allowance is a placeholder for something not yet chosen, and low allowances make a low total that grows later.
Tie payments to observable milestones, never to calendar dates, and keep a meaningful final payment until the punch list is cleared.
This is general information from a builder’s perspective, not legal advice. For a contract of significant value, have an attorney review it.

What clauses does every contract need?
| Clause | What it must actually say |
|---|---|
| Parties | Legal business name, address, registration details — not a trading name alone |
| Scope of work | Room by room, item by item. “Renovate kitchen” is not a scope |
| Drawings and specifications | Listed by title and date, and incorporated into the contract |
| Exclusions | What is explicitly not included. Read this first |
| Price and allowances | The total, and every allowance itemized with its assumed value |
| Payment schedule | Tied to milestones, with amounts and what triggers each |
| Change orders | Written, priced, signed before work proceeds |
| Schedule | Start date, substantial completion, and what legitimately extends it |
| Permits | Who pulls them and who pays for them |
| Insurance | Coverage carried, with certificates to be provided |
| Lien waivers | Provided as subcontractors are paid |
| Warranty | Duration, what is covered, what is excluded |
| Site conditions | Hours of work, access, protection, cleanup, waste |
| Dispute resolution | The process before anyone goes to court |
| Termination | How either party ends it and what is owed at that point |
Scope deserves the most attention. “Renovate primary bathroom” can honestly mean fixtures replaced in the same positions, or it can mean a room taken to the studs and re-planned. Those are different projects at different prices, and a vague scope means the contractor prices the cheaper reading while you picture the other.
Allowances, and how they hide risk
An allowance is a sum set aside for something not yet selected — tile, plumbing fixtures, lighting, hardware, appliances. It is a legitimate device and it is where low bids come from.
- Every allowance should be itemized, with a quantity and a unit rate, not a lump sum.
- Ask what the allowance actually buys. A tile allowance quoted per square foot means nothing until you know whether it includes setting materials and labor.
- Test the number. Go and look at what that rate buys at a real supplier before signing. This takes an afternoon and is the single most useful thing you can do with a contract.
- Understand what happens if you go over — and under. Some contracts credit an underspend; many quietly do not.
- Reduce allowances by deciding early. Every item you select before signing becomes a fixed price rather than an estimate.
The deeper mechanics of how budgets drift are in change orders and budget control.
A contract is only as good as the drawings behind it. Where the plan, the elevations and the specifications are complete, the scope is unambiguous and the allowances are few.
Jan Revels draws the project and builds it under one contract, so there is no gap between what was designed and what was priced.
Payment schedules that protect you
- Milestones, not dates. “On completion of rough-in and passing inspection” is observable. “On the first of the month” is not tied to progress at all.
- Payments should trail the work, not lead it. You are paying for what has been done.
- A deposit is normal, and it should correspond to materials ordered and time committed rather than being an arbitrary fraction.
- Keep a meaningful final payment. Once the balance is paid, your ability to get the punch list finished depends entirely on goodwill.
- Define substantial completion. The point at which the space can be used for its intended purpose, with only minor items outstanding. Without a definition, this becomes the most argued sentence in the project.
- Pay the contractor, not the trades, unless the contract explicitly provides otherwise.
The change-order clause
Changes are normal. On any remodel of an older house, some are unavoidable — a wall opens and there is something behind it. What matters is the process:
- In writing, describing the change specifically enough that a stranger would understand it.
- Priced, with the cost broken out rather than a lump sum.
- Schedule impact stated. A change that adds two weeks needs to say so before you approve it.
- Signed by both parties before the work is done. This is the clause that protects everyone.
- A running total of the contract sum after each change, so nobody has to add them up in month four.
Resist verbal approvals, including your own. “Just go ahead” said in a hallway is the origin of most billing disputes, and it is unfair to both sides.
Why do liens matter here?
This is the risk homeowners most often have never heard of. In Texas, a subcontractor or supplier who has not been paid can file a lien against your property — even if you have paid your general contractor in full. If the contractor did not pass the money on, the exposure lands on your house.
The protections:
- Require lien waivers from each subcontractor and major supplier as they are paid, as a term of the contract.
- Ask who the major subcontractors and suppliers are at the start, so you know who could file.
- Keep records of every payment, with dates and what each covered.
- Take notices seriously. Texas has a notice process before a lien is perfected; correspondence from a subcontractor you have never dealt with is not junk mail.
- For a project of significant value, have an attorney review the contract. Lien law is state-specific and this is exactly the kind of exposure worth an hour of professional time.
What to add if it is not there
- Working hours and access, so expectations about a 7 a.m. start are set in advance.
- Site protection — floor covering, dust barriers, and daily cleanup, specified rather than assumed.
- Where materials are stored, and who is responsible if they are damaged or stolen on site.
- Photographs of concealed work before it is covered. Free to take, invaluable in five years.
- A closeout package — permits, inspections, warranties, paint colors and product specifications.
- Communication protocol — one point of contact, and a stated response time.
- Punch list process — how it is compiled, and how long the contractor has to clear it.
Key takeaways
- A vague scope is priced at the cheapest honest reading of it. Be specific.
- Read the exclusions before the inclusions.
- Go and see what each allowance actually buys before signing.
- Payments tied to observable milestones, trailing the work, never leading it.
- Define substantial completion in the contract, or it will be argued about.
- Change orders in writing, priced, with schedule impact, signed before the work.
- In Texas an unpaid subcontractor can lien your house even if you paid in full. Collect waivers.
