Masonry Restoration Cost Calculator
Tuckpointing and stone repair for historic masonry.
About this calculator
This calculator estimates the total cost of restoring historic masonry by breaking the job into four cost centers, each priced off a fixed per-square-foot rate: repointing (tuckpointing deteriorated mortar joints) at $18/sq ft — priced above generic mortar work because historic masonry typically requires lime-based mortar formulated to match the original's softness and vapor permeability, since modern Portland cement mortar traps moisture and accelerates spalling in old brick and stone. Stone or brick repair/replacement (dutchman repairs and unit swaps) runs $60/sq ft, and cleaning — when toggled on — is a flat $5/sq ft applied to the entire wall face, not just the visibly soiled area. Scaffolding is likewise priced across the full wall area at $8/sq ft, since access equipment has to reach the whole facade regardless of how much repointing or stone repair is actually needed.
Only the repointing and stone-repair line items scale down with your percentage inputs; cleaning and scaffolding always apply to 100% of the entered wall area. These are national ballpark rates for planning-stage budgets — actual bids vary substantially by region, mortar formulation, stone type, and building height, and this tool doesn't distinguish between brick, limestone, sandstone, or brownstone, which can have very different repair costs. Use it to compare treatment scope trade-offs and set a rough total before getting contractor quotes, not as a substitute for a site-specific estimate.

How to Use This Calculator
- Enter the total Wall area (sq ft) of masonry to be treated based on field measurements.
- Estimate Repointing % — the percentage of mortar joints that are deteriorated and need tuckpointing with compatible lime mortar.
- Enter Stone repair % for the percentage of stone or brick units requiring dutchman repairs or replacement.
- Toggle Cleaning (1=yes) if the masonry needs gentle cleaning — chemical or pressure washing to remove biological growth or staining.
- Review Total restoration cost, Repointing cost, and Stone/brick repair cost to allocate the restoration budget by trade.
- Use Cost per sq ft and Scaffolding cost to complete the project estimate for owner and contractor negotiations.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersWall area (sq ft) = 1000, Repointing % = 30, Stone repair % = 5, Cleaning (0 or 1) = 1 = 4 input(s) provided
- Calculate Total costTotal cost = repointCost + stoneRepairCost + cleaningCost + scaffoldingCost21400 = $21,400
- Calculate RepointingRepointing = round(repointArea * repointCostPerSf)5400 = $5,400
- Calculate Stone/brick repairStone/brick repair = round(stoneRepairArea * 60)3000 = $3,000

Frequently Asked Questions
Why is repointing priced at $18/sq ft here instead of a cheaper generic mortar rate?
Historic masonry usually needs lime-based mortar rather than modern Portland cement, because lime is softer and more vapor-permeable and won't trap moisture inside old brick or stone the way cement mortar does. That specialty mortar and the skilled labor to match the original joint profile cost more than routine tuckpointing, which is why this calculator uses $18/sq ft on the repointed area instead of a generic repair rate.
Why do cleaning and scaffolding cost the same no matter how much repointing or stone repair I need?
Cleaning is applied as a flat $5/sq ft across the entire wall area you enter, not just the portion that looks soiled, and scaffolding at $8/sq ft is likewise costed against the full wall face because access equipment has to reach the whole facade regardless of how localized the actual repair work is. Only the repointing and stone-repair line items scale down when you lower their percentage inputs — cleaning and scaffolding always apply to 100% of the wall area.
Does this calculator distinguish between brick, limestone, sandstone, and brownstone?
No — it applies the same $60/sq ft stone/brick repair rate and the same cleaning and scaffolding rates regardless of material. Different stone types have very different repair costs in practice (sandstone and brownstone in particular are often more labor-intensive to match and repair than brick), so treat this tool's total as a planning-stage ballpark and get material-specific contractor quotes before finalizing a budget.
What does Cost per sq ft actually represent?
It's the total restoration cost divided by the total wall area you entered, giving an average blended rate across repointing, stone repair, cleaning, and scaffolding — not the cost of any single trade. It's useful for comparing this project's overall cost density to other jobs or industry benchmarks, but it won't tell you the per-square-foot cost of, say, just the stone repair.
