Contractor Quote Checklist
Masonry Foundation Repointing Quote Checklist Before Repair
Short answer: Approve a masonry foundation repointing quote only after it identifies the wall areas and moisture causes, documents the existing masonry and mortar, specifies compatible replacement mortar, defines joint removal and preparation, includes a representative sample panel, states weather and curing limits, protects adjacent work, and closes with cleaning, inspection, records, and a written warranty.
Repointing is more than filling visible gaps. Mortar hardness, vapor movement, joint profile, removal technique, wall saturation, temperature, and curing affect whether the repair protects the foundation or damages the brick and stone around it.
Do not compare bids by square footage alone. One mason may include moisture diagnosis, mortar testing, hand removal, deep joint preparation, sample approval, staged curing, and selective unit replacement while another may price a thin surface application over deteriorated mortar.
Document The Wall And The Cause Of Deterioration
Ask for an elevation or marked photo showing open, cracked, eroded, previously patched, painted, wet, bulged, and sound areas. The quote should address roof runoff, grading, splashback, plumbing leaks, rising damp, freeze-thaw exposure, and failed coatings before new mortar hides the evidence.
National Park Service guidance says the cause of mortar deterioration should be determined before repointing. Separate drainage, structural movement, masonry-unit repair, and coating removal from the joint work so every bidder prices the same limits.
Match Mortar To The Existing Masonry
Require the mason to describe the existing brick or stone, bedding mortar, pointing mortar, prior hard patches, and the proposed binder, aggregate, color, texture, compressive behavior, and joint profile. Older or softer masonry can be damaged by an incompatible mortar that is too hard or too impermeable.
For historic or uncertain assemblies, ask whether samples will be analyzed and who approves the replacement mix. A color card alone does not establish compatibility; the cured sample should be evaluated in the actual wall and lighting.
Define Joint Removal And Preparation
The scope should state which joints are removed, target depth, hand-tool or controlled-tool method, protection against chipped units, cleaning method, and how dust and debris are removed before placement. Thin skim pointing over loose material is not a durable scope.
GSA's historic masonry procedure calls for damage-free mortar removal and gives joint-depth criteria while warning against compromising wall stability. The contract should require approval before cutting methods or depths change in fragile areas.
Approve A Representative Sample Panel
Set the sample panel location and size, and require it to demonstrate removal, joint preparation, mortar color, aggregate, texture, profile, tooling, cleaning, and cured appearance. Keep the approved panel in place as the workmanship standard.
State who can approve the panel and what happens if the first mix or technique is rejected. Production work should not begin until the sample has cured long enough for a meaningful comparison.
Control Weather, Placement, And Curing
The proposal should state acceptable wall and air conditions, wind and sun protection, pre-wetting method, lift or packing sequence, initial tooling, misting or damp curing, coverings, and pause rules for rain, freezing, excessive heat, or rapid drying.
Add a schedule allowance for curing rather than treating protection as an optional extra. Also define temporary covers, pedestrian barriers, plant protection, daily cleanup, and how occupied basement openings or utilities will be kept safe.
Inspect, Clean, And Close Out The Work
Before final payment, walk every elevation for full joints, consistent profile, cracks, smears, chipped units, blocked vents, disturbed flashing, incomplete edges, and damage to windows, plants, paving, or interior finishes. Aggressive acid or abrasive cleanup should not be an unapproved shortcut.
Collect the final mortar mix record, sample or laboratory information, marked repaired areas, product data, progress photos, change orders, cleaning method, maintenance instructions, and warranty. Record excluded cracks or movement so future changes can be distinguished from the completed repair.
Masonry Foundation Repointing Scope Comparison
| Quote area | What to confirm | Why it matters |
|---|---|---|
| Survey and diagnosis | Marked wall areas, moisture sources, movement, coatings, prior patches, and unit damage | Prevents new mortar from covering an unresolved cause |
| Mortar compatibility | Existing mortar review, proposed binder and aggregate, strength behavior, color, texture, and joint profile | Protects softer masonry and supports a compatible repair |
| Removal and preparation | Joint limits, depth, tools, edge protection, dust removal, cleaning, and unstable-wall stop point | Distinguishes full preparation from surface pointing |
| Sample panel | Location, size, mix, tooling, cleaning, curing time, approver, and acceptance standard | Creates a visible benchmark before full production |
| Weather and curing | Temperature and moisture limits, pre-wetting, lifts, covers, damp curing, rain, wind, heat, and freeze pauses | Reduces rapid drying, washout, and weak joints |
| Closeout | Inspection, gentle cleaning, damage repair, mix record, repaired-area map, photos, maintenance, and warranty | Leaves a traceable repair and enforceable finish standard |
Questions To Ask Before Approval
- Which joints and masonry units were inspected and marked for repair?
- What moisture source or movement caused the deterioration, and is its correction included?
- How will the proposed mortar be matched for composition, behavior, color, texture, and profile?
- What joint-removal depth and tools will be used around fragile brick or stone?
- Where is the sample panel, who approves it, and how long will it cure before production?
- What weather, pre-wetting, protection, and curing rules are included?
- Which records, repaired-area map, cleanup inspection, exclusions, and warranty will I receive?
Red Flags In This Quote
A price to grind and fill every joint without diagnosis, mortar compatibility, or fragile-unit protection can turn a maintenance repair into masonry damage.
A thin cosmetic smear over loose mortar with no specified removal depth or sample panel is not a comparable repointing scope.
Production scheduled through freezing, heavy rain, hot sun, or high wind with no pause and curing plan shifts avoidable weather risk to the wall.

FAQ
Is tuckpointing the same as repointing?
The terms are often used interchangeably in sales, but repointing means removing deteriorated joint mortar and installing new mortar. Ask the quote to describe the actual removal, preparation, and replacement process.
Should all foundation joints be repointed?
Not automatically. A condition survey should distinguish failed joints from sound mortar and identify movement, water entry, coatings, and damaged units that need a different repair.
Why does mortar compatibility matter?
The mortar must work with the brick or stone. An overly hard or impermeable replacement can concentrate stress and moisture in the masonry units rather than the sacrificial joints.
Why require a sample panel?
A cured sample shows the proposed color, aggregate, profile, texture, cleaning, and workmanship on the actual wall before the same method is repeated widely.
What should a repointing warranty cover?
Ask for a written term and remedy for failed adhesion, cracking, washout, inconsistent or incomplete joints, cleanup damage, and workmanship, plus clear exclusions for documented structural movement or unresolved water sources.
